The Porsche 928 was first unveiled at the Geneva Motor Show in 1977, it then went on sale later that year as a 1978 model.

At first some hardcore Porsche fans rejected it as the design was so far removed from traditional Porsche values but despite this it went on to win ‘car of the year’ and was the first sports car to do so. The 928 was the bigger brother to the 924 with a more powerful engine, a 240 bhp 4.5 litre water-cooled V8 which gave excellent performance. The body work was more rounded off with fared-in impact bumpers to streamline the shape which gave it a futuristic design. Other state of the art technology included corrosion-resistant aluminium panels, self-adjusting valves and 12,500 mile servicing. The rear wheels were driven via a rear-mounted transmission improving weight distribution.

In 1981 the 928S was produced, with subtle styling modifications and a much needed 25 percent increase in power to 300bhp to compete with other manufacturers at the time. The increase in power came through an enlarged 4.7 litre engine, the compression ratio was also raised and camshafts re-profiled.

The 928 S4 was introduced in 1987 with more power via an additional increase in engine capacity to 5.0 litres. The engine produced 316 bhp with 4 valves per cylinder, modified cylinder heads and larger valves. This really boosted performance with 0-60 dealt with in 5.7 seconds and a top speed of 165 mph. Around 80 S4′s where built with the very desirable 5 speed dog leg gearbox. The styling also became a little smoother with flush-fitting lights, a rear spoiler which was fold-able on the first S4′s and an integrated spoiler at the front. To make the cars more user friendly they now came with extras like leather trim, central locking and split folding rear seats. The brakes were especially effective and believed to be better than any other production car of its time. There were many reviews in its day that said this 928 could well be the most efficient handling car produced of the era.

To think the first 928′s appeared in the late 70′s is quite the surprise considering how well the design has survived; especially true of this example presented in a shimmering metallic of Diamond Blue. Free from stone chips and with a deep lustre the car presents very well indeed. Panel fit is straight and true with lights, trim and seals upholding excellent integrity and shape pointing to a pampered ownership history.

The side, rear glass and windscreen are clear and free of any cracks and chips.


This particular car has a blue / cream interior, including even the roof lining which really marks this cabin from the rest with a true era specific colourway. The leather seats provide excellent support and are free from rips and tears with just some age related creases on the drivers bolster as you would expect. The rear seats are also in excellent condition and provide cocooning accommodation for smaller passengers, with rather unique rear sun visors to protect necks from the large heated rear glass screen. The glass at the rear not only defines the look of the car but also gives the interior a wonderful feeling of space allowing this Porsche to truly fulfill its continent crossing GT role.

An 8 speaker system and Pioneer stereo provide a great sound though you may will be tempted to dip the electric windows or crack open the electric sunroof to enjoy that delightful V8 rumble.


Boasting 4 valves per cylinder and Bosch fuel injection this 928 surges forward on a wave of torque making progress truly effortless. Thanks to a rich history of OPC maintenance the performance and presentation remains excellent.

Having had a recent fluid flush and replacement, the 4-speed automatic box is smooth and precise pulling through all the gears as you would expect.


Sitting on the correct 16” alloys the wheels really capture the spirit of the era and are presented without any marks on the rim. Pirelli’s to front and Toyo tyres to rear display plenty of tread.

With recent ABS sensors the car pulls up to a stop in sharp straight line with no adverse pitch or pull.


The original service book states PCGB as the first owner from April 1989. Main dealer maintained to 2006, this S4 has had everything it has needed when pressed into service alongside professionally maintained storage when not in use.

Cambelts, Rollers and Aux belts, as well as Oils and filters, have all been replaced within the last 1,500 miles whilst the Constant Velocity gaitors have just been renewed.

The original Porsche book pack is complete whilst 12 Months MOT will be applied upon sale.
