03-reg Petrol, Owner for More than 5 years

It had an engine failure at 15000 miles that cost £5000.00 to fix. Apparently 5% of this model have the problem. A bearing fails in the engine causing all sorts of damage. Porsche and the dealers know all about it but don't tell the owners until it has happened. Don't trust Porsche. It is caused by a designe fault in the bearings. So much for engineering excellence. The electric hood lift also failed in the first two weeks stranding my wife in a car park in the late evening. Bad assembly. Porsche dealers bodged the fix. It was finally fixed after the car came out of warranty by a specialist Porsche after market workshop. I would never buy another Porsche.

A NEW ENGINE REQUIRED AFTER 30000 MILES WITH FULL SERVICE HISTORY. TWO NEW HEAD UNITS. NEW AMPLIFIER. FAULTY EARTH POINT ON VANITY MIRROR LIGHTS. CORRODING WHEELS.
THIS WORK HAS COST £15000 WITHOUT OTHER RUNNING COSTS.
NOT ACCEPTABLE - NO SUPPORT FROM PORSCHE DUE TO CARS AGE EVEN THOUGH LOW MILAGE. MAIN DEALER (BOURNMOUTH) VERY GOOD. INSTALLED NEW ENGINE AND COMPLETED ALL OTHER WORK REQUIRED.

Has had to have 2 engine rebuilds and still an unfixed noise persists, also had a new gearbox, new door electrical components, and other smaller failures. The fuel consumption is poor but I recognise that it is a sports car and hence this is understandable. a similar story with parts, tax and insurance, however hourly labour rates at porsche dealerships are absolutely ridiculous (expensive).

Absoloutely Nothing so far,owned last two years,milage only 12,000

I have Owned Porsches for 20 yrs,technically this car is the best in road holding and performance is brilliant, while having owned the 944 turbo for 16 years it was more practicalbut as I use this only as a second car its not a problem and I remain a fussy owner as the car must be right and would be critical if deserved.

I do my own service using mobil oil and changing yearly regardless of mileage I think that contibutes greatly to its reliability. I use spares from my local factors and only supplies quality parts without paying main dealer prices. Because its not covering much mileage I dont find running costs a problem. I count the cost in smiles/miles.

The driving experience is incredible - an absolutely enthralling car to drive. Reliability has been well below what I would expect - you do not expect a German car to need new shock absorbers after only 20,000 miles. The car has also developed a number of rattles and does not age particularly well.

A well-designed and engineered piece of machinery that upholds Porche's reputation for quality. Exceptional weight distribution provides near-perfect balance. It's a really fun indulgence.

Broken rear coil spring and a flat battery just after I bought it. no other problems. No worse than I would expect for this car. 18 inch wheels definitely much cheaper than 19 inch.

Nothing major has gone wrong in past 6 years! Fuel is no more than expected and better than many sports cars. parts seldom bought due to excellent reliability.

I've had virtually no problems with the car. For what it is it's incredibly economical and I spend almost nothing on it apart from regular servicing.

Faultless :o). The low mpg is cancelled out by build quality and reliability.
