As the last of the air-cooled 911s, the 993 is a special model for many fans
Classic Porsche 911 993 Review
The Porsche 993’s cabin is a fine place to be, with the traditional five-dial instrument pack (dominated by the rev counter) and a less scattergun approach to the positioning of the switches and minor controls than on previous models. The plush interior is also beautifully assembled, with a feeling of real quality to all of the materials.
On the road, the experience is as impressive as you’d expect from this potent car. Even if things are a bit more civilised than with earlier incarnations, you know straight away that you’re piloting one of the finest sports cars around. The noise of the air-cooled engine may have been muted slightly, but it’ll still raise the hairs on the back of your neck at full chat. And all this is accompanied by delightfully accurate power-assisted steering, powerful brakes and a real feeling of security from the multi-link rear suspension. It still demands a degree of respect, but make no mistake, the 993 is a proper 911.

WHAT TO LOOK FOR
BODYWORK & CHASSIS
You should be aware that 911s are popular track day machines, so be sure to scrutinise the car and its history for any signs of previous accident repair. Lift the carpet in the front luggage compartment and check for evidence of new panels or for any tell-tale creases in the floor or inner wings, and look out for signs of new welding. Also inspect for damp in the luggage compartment, checking around the battery for corrosion, and make sure the tyre compressor is present.
The galvanised bodyshell resists corrosion well on the whole, but there are a few spots to check. Stone-chipping around the nose and headlamps is common, and make sure there is no bubbling around the front or rear windscreens – poorly fitted replacements can cause rust to develop. Check the panels aft of the wheels for paintwork damage from road debris, and ensure that the bumpers are secure – the mountings have been know to rot. Make sure the electric rear spoiler operates properly (it was fixed on RS and Turbo models), and take a look at the door check-straps – they can pull from their mountings as the doors were heavier than on previous models and a proper repair is pricey.
ENGINE
The 3.6-litre M64 engine is strong, but it needs proper maintenance, so avoid cars that aren’t accompanied by a perfect service history. The M64 is less prone to oil leaks than the later water-cooled engines, but check for signs of leakage all the same; regular oil changes are essential. If it’s not been done already, most engines will be ready for a rebuild around the 80,000-100,000-mile mark – the top end particularly – so budget accordingly. A smoky exhaust should be treated with extreme caution on any model, but pay particular attention on the Turbo – the twin KKK blowers give plenty of power and will have most likely been worked hard in the car’s lifetime. Post-1996 models received the Varioram variable inlet system for increased power and torque.
ELECTRICS
The 993 was available in cabriolet and Targa-roofed forms. On the former, check for hood damage and a cloudy plastic back window. Replacement is costly and non-Porsche items often don’t fit as well. On Targas, ensure the glass roof panels slide as they should, as the electrics can play up.
RUNNING GEAR
The six-speed manual gearbox – designated G50 on C2 models and G64 on 4WD cars – is tough, but prolonged track abuse can eventually take its toll. Make sure the gearshift action is slick and be alert for any whines, weak synchromesh or clutch slippage. The four-speed Tiptronic automatic ‘box wasn’t admired by everyone, but it is reliable on the whole – which is just as well, since replacing one will easily run into thousands of pounds. The 4WD system is generally trouble-free so long as it is maintained properly, but don’t ignore any dashboard warning lights.
BRAKES
The 993 is very sensitive to correct wheel alignment and setting the geometry needs specialist tools – odd handling or uneven tyre wear requires further investigation. A complete suspension refurb can easily cost £3000-4000 and wear isn’t always apparent, so a professional inspection is advisable. Watch for scored and corroded brake discs and check the condition of the Brembo brake calipers; they contain a steel section that can corrode, causing the pads to stick. Ensure the ABS warning light illuminates and extinguishes as it should, too.
INTERIOR
Interior trim materials and build quality is top-notch, so it’s mainly a case of inspecting for wear and tear. Make sure everything works, particularly the electric seat motors, and check for any damp caused by blocked drain-holes or leaking windscreen seals. Air-conditioning was a desirable option when new, so ensure that both it and the heater are working properly – a worn air-con pump or rusty heat exchangers are the main causes of problems.
OUR VERDICT
The 993 is seriously desirable, perhaps more so being the final recipient of the classic air-cooled engine. As with all older 911s, you’ll need to tread carefully if huge expense is to be avoided. Get a specialist inspection if you’re in any doubt about a car’s condition or provenance, but a cherished example of this legendary sports car will be an absolute joy.
