Porsche 928: buying guide and review (1977-1995)

For years the Porsche 928 languished in the shadow of the 911, but recently things have been changing for the water-cooled V8-powered GT. Looking back now, it’s amazing to think that the 928 was so unloved for many years, with depressed values to match. This is no longer the case.
 
When it was launched, the original design was so advanced that the 928 remained in production - basic design effectively unchanged - for around 17 years. Of course the 928 evolved over the years wit added spoilers, more equipment and and more power, but the basic formula of quick and comfortable continent-crushing ability remains a constant through the range. What’s not to like? 
 
‘Thirst and complexity’ are the usual retorts. It’s true that 20mpg is a best-case scenario for any 928 – but with most of the survivors now being kept as second cars, that’s less of an issue. And while there seems to be an awful lot of engine shoehorned under the bonnet, it’s really a straightforward design that can rack up enormous mileages. 
 
Of course, the 928 was an expensive car when new, with commensurately high servicing bills. But today’s non-franchised specialists charge more reasonable prices and there are plenty of secondhand parts around – sadly, good cars are still being stripped out for track day or race use. 
 
Despite its recently discovered potential as a racing car, the 928 was always marketed as a GT and about 80 per cent were sold with automatic transmission. Manuals are now sought after for track days, but the 928’s big V8 is ideally suited to an auto ’box and gives a relaxing drive. 
 
Which one to buy?
 
Chances are that if you fancy a 928 you’ll already know what you want: either the design statement of the original car (no spoilers, no side strips, Pascha interior, telephone-dial alloys) or the sheer speed and greater luxury of the S4-and-later models. Buyers tend to fall into one or other camp. 
 
The late-’70s cars are by far the rarest now and are the only 928s likely to have any longterm investment potential. They are not particularly fast by modern standards but they’re the simplest and cheapest to run. 
 
Moving on a few years, a 1980s S or S2 still has a certain period appeal, retaining the egg-shaped rear of the original car. Among the restyled cars, the S4 is the sensible buy – as its engine is bulletproof – while the GTS is the most hardcore and most expensive to fix, having unique brakes and engine.

Common problems
 
• The 928 bodyshell was galvanised right from the start of production, so structural rust is rare. Early cars will typically show the odd bubble around rear windows or hatch (where trim clips have broken the galvanising), but usually corrosion is restricted to paint scabbing on the alloy bonnet, front wings and door skins. 
 
• Mechanical parts also last well. Cambelt failure is the biggest danger: on 4.7-litre and later engines the valves can then collide with pistons (4.5s aren’t affected). The belt should be changed every four years or 60,000 miles. It’s wise to renew the water pump at the same time. 
 
• When the GTS was launched, a number of engines suffered from excessive oil consumption due to porous cylinder liners. Many cars had new engines from Porsche, however if the car you’re looking at wasn’t one of them, ask the owner about oil usage. If it uses an excessive amount today it could spell big bills in future. 
 
• The 928’s suspension hardly changed during production, which means that you could, in theory, fit GTS suspension to a 1970s car. OE-spec dampers are now hugely expensive, although specialists do offer aftermarket sets for considerably less. 
 
• The 928 has its gearbox mounted just ahead of the rear diff, and it’s connected to the engine by a torque tube. Manual ’boxes don’t have the sweetest changes but are tough, while the automatics are Mercedes-Benz units, so very reliable. However, failure to check the flex plate tension regularly can lead to a worn crank thrust bearing and, ultimately, a wrecked engine block. 
 
• 928s do suffer electrical gremlins if not driven for any length of time, but the wiring is actually quite easy to trace. Make basic checks on the operation of the electric windows, mirrors, seats, headlights and central locking, as these could be costly to rectify if paying a specialist. 
 
• Air-conditioning will rarely work on an older car and may cost £500-600 to repair. Interiors last pretty well but the 1970s pyschedelic-check trim known as Pascha eventually falls apart at the seams. While good condition second hand items are nearly impossible to find, reproduction fabric is now available through specialists. 
 
Model history

1979-1984: 928S gains bigger, 4.7-litre engine, plus small front and rear rubber spoilers and side-protection strips. Power now 300bhp and top speed 152mph.
 
1984-1985: S2 has 310bhp; auto option now a four-speed.

1985: US-only cars gain new 5-litre V8 with DOHC , four-valve heads and unofficial ‘S3’ title. 
1986-1992: S4 restyled with smoother front end, wraparound tail-lights and big rear spoiler. 5-litre V8 already used in States gives 320bhp. Digital dash and auto ’box standard for ’89-on S4.

Summary and prices
 
Porsche 928 prices have been generally very steady for the past decade, with a very gentle upward trajectory for the most desirable examples. To some extent, the condition is more important than model or year. A superb car, early or late, might sell for up to £15,000, but good usable examples start at around £5000. 
 
Very early cars start from around £3000 for something needing work (although projects can still be picked up from £1000), with the later models becoming more expensive as the power and spec levels increase. The advice is to steer clear of anything too cheap, as the potential bills associated with these will often be substantial.
 
The most valuable is the high-performance GTS model, with prices usually starting from £8000-£15,000. Perfect examples, especially with low mileages, are often advertised at more than £30,000.

    POA POA

    The Porsche 928 was a front-engined sports-GT sold from 1978 to 1995 and was an immediate hit with demand in the UK far outstripping supply. Originally intended to replace the company's iconic 911, the 928 attempted to combine the power, poise, and handling of a sports car with the refinement, comfort, and equipment of a luxury saloon to create what some Porsche executives thought would be a vehicle with wider appeal than the compact, quirky and sometimes difficult 911. The 928 qualified as a 2+2, having two small seats in the rear which could be folded down to enlarge the luggage area and both the front and rear seats had sun visors for occupants. Porsche's design and development efforts paid off during the 1978 European Car of the Year competition where the 928 won ahead of the BMW 7-series and the Ford Granada. The body, styled by Wolfgang Möbius under guidance of Anatole Lapine, was mainly of galvanized steel but the doors, bonnet and boot were made of aluminium to save weight. Polyurethane elastic bumpers were integrated into the nose and tail and covered in body-coloured plastic; an unusual feature for the time that was intended as both a styling feature and to reduce drag.

    The Porsche 928 is a luxury GT car produced from 1978 to 1995. Originally intended to replace the company's well-known and famed 911, the 928 combined the power, poise, and handling of a sports car with the refinement, comfort, and equipment of a luxury sedan to create what some Porsche executives thought would be a vehicle with wider appeal than the compact, quirky and sometimes difficult 911. Since its inception in 1949, Porsche has manufactured only seven front-engined models, four of which were coupes, including the 928. The car has the distinction of being the company's only coupe powered by a front-mounted V8 engine, and the company's first production V8 powered model.
