JZM Porsche: the only UK specialist with Porsche PIWIS III

Our new Porsche PIWIS III diagnostics systems and PIWIS III tester arrived at the end of December. We’ve been enjoying the huge increase in speed and agility offered by the latest Porsche systems and reaping the benefits of our Porsche PXN access and daily software updates.

“PXN stands for Porsche (e)Xternal Network,” says JZM technical director, Steve McHale. “This means that our new machines log in to the main Porsche factory network and have access to all the latest technical updates and coding capabilities. It is impossible to work on Porsche’s very latest cars without this technology.”

JZM has invested in factory training and official diagnostic technology since 1973, when Steve did his first official Bosch training course. Since then, we have maintained a close relationship with the technical team at Reading and regularly attend the manufacturer’s courses. Two of our team went for training on the new PIWIS III system.

“Porsche tell us that JZM is the only specialist on the UK mainland using PIWIS III. That’s not a huge surprise when you consider the costs involved,” says Steve. “It’s easy to buy some second-hand manuals, watch a few DIY videos online and start selling yourself as a Porsche specialist, dealing only with air-cooled and early 996s, but the newer cars are so technically sophisticated that it is impossible to do anything without having the proper technology to talk to every ECU. This costs money that small operations simply do not have. Our technical partnership with Porsche goes back decades, so it is something we have always factored into our business.”


A good example of how important this is to JZM was a recent repair to a 991 Turbo. These cars have active rear wheel steering, which is controlled by an ECU: one for each side. A bodyshop repairing damage to a 991 Turbo had changed a damaged rear steering arm, but there was no way to tell the car what had happened, so the car was showing all kinds of errors. We had to recode the entire car to let it know that something had been replaced.

PIWIS III brings serious computing power to Porsche diagnostics, so much so that the older cars including late 997s simply do not talk to the system quickly enough and have to be reset manually. Newer cars have a lightning-fast onboard network, saving valuable hours in diagnostics when problems arise. This new system is incredibly quick and automatically downloads daily software updates from the factory. If something pops up that we’ve not seen before, we can send the data to Reading and on to the factory until we get a solution. We also see at a glance whether a car has had all of its recall campaign updates applied.

We’re delighted with the new systems and are pleased to offer the Porsche PXN service to all of our customers at no extra charge above our regular fixed-price servicing. Contact service@jzm.south.co.uk to discuss your Porsche maintenance needs.

JZM Porsche Pre-Purchase Inspection Service

It’s a big mistake to buy any Porsche without first inspecting it thoroughly, to be assured of proper condition. That’s why you should talk to JZM Porsche about our PPI service (pre-purchase inspection).

JZM Porsche Pre-Purchase Inspections

We carry out many pre-purchase inspections for prospective Porsche buyers every year. Inspection is reasonably priced at standard workshop rates. Cars can be brought to our workshop, where the inspection will be completed by a trained JZM technician while you wait. The technican will compile a report and discuss his findings with you afterwards. The results will either confirm the car as a good one or offer some areas for improvement, which could be a help in price negotiations.

In the most extreme cases, we may advise against purchase, but the final decision rests with the buyer. Whatever happens, you will have the best information at your disposal, to help with the decision and avoid losing money on a bad car. Email the JZM Porsche service department to enquire about our Porsche pre-purchase inspections or call us on 01923 269788.

Don’t forget those Porsche Winter Checks


Winter is just around the corner. The AA said it received over 10,000 calls on the first real day of UK cold weather, so now is the time to book a service and check all is in order for the cold dark months ahead. Essential checks include tyres, battery and charging system, climate control to keep cabins warm and dry with glass demisted, lighting and windscreen wiper systems and weather seals and hood drains on roadster and cabriolet models.

This smart 996 Turbo S Cabriolet seen here was already wearing its factory hardtop when it visited JZM Porsche for a pre-winter service. Danny went through our service checklist (now managed on tablet devices) and found very little to worry about on this excellent example.

Long term storage does more harm than good, so it is always great to see people using their Porsches on a regular basis. That said, daily familiarity with a car makes it easy to miss simple defects that can cause unnecessary upset when the weather turns bad. Contact us today to discuss a pre-winter inspection on your Porsche.


Manthey Porsche wheels sold to Canada

JZM sells only the highest quality Porsche tuning parts – why fit anything less to the world’s greatest sports cars? Alongside our sales of genuine Fuchs wheels, KW Suspension, JZM/Surface Transforms ceramic brakes and Akrapovic titanium exhausts, JZM Porsche is the UK distributor for Manthey Racing. We ship Manthey parts to Porsche enthusias
ts all over the world and we recently sent a very handsome package to Canada, in the form of a set of Manthey Racing BBS forged wheels for a Cayman GT4.

Used to great effect on the Manthey Racing Cayman GT4 Club Sport, the Manthey alloys are a version of the beautiful BBS F1-R forged aluminium wheels. Manthey reports that more than 11 kilos of unsprung weight may be saved when using these rims in place of original wheels. Available in silver, titanium or black, they can also be supplied in a centrelock version to suit the 991 GT3. Email parts@jzm.south.co.uk to find out more.


Rare RHD Porsche 993 Turbo S for sale

Air-cooled 911s continue to be highly regarded by classic car investors. The record-breaking Porsche results at the recent Sotheby’s London sale reinforced interest in high end 993s, so we’re delighted to bring a real 993 rarity into stock.

The iconic 993 Turbo is a popular option for air-cooled 911 Turbo buyers, but our new Porsche 993 Turbo S for sale is a very different beast. Offered for one year only towards the end of 993 production, the Turbo S is a very well-specced Turbo with factory 450 horsepower upgrade and more add-ons than a budget airline booking form.

Just 23 of these cars were made for the UK, making the RHD 993 Turbo S a very rare car. It is an exceptionally comfortable and usable investment, not to mention a beautiful item in rare Cobalt Blue with Grey leather sports trim. Contact us today!


Porsche 991 GT3 RS for sale at JZM

It’s always a pleasure to have the latest, greatest Porsche 911 available from stock, so we’re delighted to welcome this perfect Porsche 991 GT3 RS for sale to the JZM showroom.

Newly arrived from Hong Kong, this perfect Lava Orange RHD example has covered less than 600 miles since manufacture. We’ve completed the import process and the car is ready to be used and enjoyed: the next owner will be its first registered UK keeper.

Cars like this are few and far between. Contact us to arrange inspection at the earliest possible opportunity. Part exchange, finance and export sales are a pleasure.



Track Day setup for a 991 GT3

JZM Porsche is well established as the UK’s premier Porsche GT3 specialist, which means that we get a lot of Porsche GT2s and GT3s in the workshop for tuning and track day setup on our Hunter laser alignment ramp. Before a car goes on the ramp, we loosen and lubricate all of the suspension components, to ensure everything can move freely as part of the setup process, and fit any new parts which our customers have asked for.

No stranger to track days, this 991 GT3 returned to the JZM workshop for setup tweaks including extra front camber. The standard Porsche arms do not permit enough movement for more aggressive setups, so we alter the geometry using a mix of Porsche components. In the case of this 991, we also had to repair and paint the underside of the front bumper, after someone forgot to use the Front Axle Lift when going over a speed hump!

Want a JZM setup on your 911? Email Steve McHale at JZM about all of our Porsche tuning products, including KW Suspension and Akrapovic titanium exhausts.



JZM Porsche Market Report September 2016

Once the kids had gone back to school and lazy August memories began to fade away, the used Porsche market awoke from its summer hiatus. We experienced a lift in sales through September, with a good mix of enquiries for all models, but especially the classics.

Sotheby’s London sale at the start of the month was a timely reminder of just how much strength still exists in the world of classic cars as collectable investments. Sotheby’s recorded almost £22 million at this event and, while classic Aston Martins and Ferraris enjoyed some very high results, prices for rare Porsche metal also raised a few eyebrows.

We’ve all heard the stories of 993 GT2 models selling for seven-figure sums behind closed doors, but as these rare cars are seldom seen at auction, it’s not been easy to gauge how high the numbers could go for the finest examples. Wonder no more, as a 12k-kilometre 993 GT2 in sublime Riviera Blue sold for £1.8 million: more than a million pounds over its top estimate with fees included.

Other Porsches sold on the night, but the knock-on effect of this single sale should not be underestimated. While some Porsche prices have fallen since the heady days of 2014, the rarest air-cooled models retain a core following. JZM has sold a number of rare air-cooled cars through 2016 and sold a few more in the days after the Sotheby’s sale, including a beautiful 993 RS in rare Midnight Blue and a very low mileage RHD Gloss Black 930.

We do not equate these results with a shift in the market, as both air- and water-cooled Porsches are still in demand. We’ve sold a number of Gen I & Gen II GT3s since our last newsletter, as well as our unregistered RHD Cayman GT4 and a very competitively priced LHD 991 GT3 RS in Lava Orange. But the strongest interest amongst investors is for rare-breed air-cooled at sensible prices.

Amongst later water-cooled cars, it is still a surprise to see so many 991 GT3 RSs priced well into the £250k bracket. Realigned prices on 997 GT3 and RS models have re-established these cars as great value against recent incarnations, so no surprise to sell a few 997s of late. That said, a well priced 991 GT3 is a fine sports car and incredible fun when tuned for fast road and track here at JZM. We sold our newest RHD 991 GT3 last week and our bargain LHD example is also expected to find a new home pretty sharpish (now sold).

Finally, a word of caution for those sellers who believe they are also entitled to a share of expected appreciation in the years ahead, and set their asking price in excess of the trade’s best advice. We say keep your expectations in check. If you want to sell, then advertise your Porsche at market rates or expect it to hang around. Buyers are super cautious right now and very few cars attract interest when priced well ahead of the market.



Porsche 993 Turbo with X50 Power & Exclusive interior

As the last of the iconic air-cooled Porsche 911 Turbos, the 993 Turbo is a favourite of enthusiast drivers and collectors alike. We are always delighted to help find new homes for the best 993 Turbos and are fortunate to have three wonderful examples in stock, ready for immediate delivery.

This beautiful Porsche 993 Turbo for sale with factory X50 upgrade is no stranger to our showroom, as we supplied the car to its current owner. Despite the curvaceous Arctic Silver exterior, it is the cabin which serves as the centrepiece of this classic Porsche, as it has been finished entirely in soft Chestnut Leather by the artisans working in Porsche’s ‘Exclusive’ workshop.

Rarely seen on everyday production 911s, the ‘Exclusive’ badge marks a car as unique. The attention to detail found in such cars is a joy to behold, and this 993’s bespoke combination of hand-stitched Chestnut leather and real carbon fibre trim really must be seen in person: photos do not do it justice! Contact us to discuss this fine example.
