R-reg Petrol, Owner for 3 to 5 years

It is not an everyday car for me - I cycle to my place of work and have a motorcyce. I bought this car, a 1997 993-series 911 (one of last air cooled model off the production line) as a future classic to use occasionally and keep long-term. Whilst I work hard keeping this car pristine, and it doesn't do many miles annually, I can imagine how it could be used for reliable performance driving every day if necessary. I have had no faults with this car that has covered 50,000 miles since new in 1997.

over-rated ownership proposition. I wasn't aware of Rear Main Real and Intermediate Shaft design faults before I bought this car. I have had the RMS replaced twice and Gearbox casing replaced twice in the two years I have owned this car. Thank goodness for tne expensive warranty. At £1450 each year, it's ridiculously expensive for a 7 year old car.

I'll never buy another a Porsche again and will not recommend this marque to my friends, family and work colleagues.

An really excellent car, although not for everyone's needs.
The only real problem is that the manufacturer has gone really silly with respect to warranty - the whole warranty is void if I get a part fitted, even by the franchise deaker, which is not exactly as the original, even if it was original equipment on a later version of the same car (e.g. Mark 2 rather than Mark 1) !!!

Porsche is now a mass market car of average quality. Manufacturer cover and support has decreased whilst running costs have significantly increased ! Damper failure at 30k miles ? Coil failure every 6 months ? Fine if you can afford to change the car every year, I won't have another one.

I have had problems with the rear wheel hubs, centre lock wheel nuts, and has been back and forth to the supplying dealer on several occasions. Running costs / fuel is more than average for this type of vehicle - servicing / dealer costs are sometimes over priced.

Persistent 2nd gear engagement issue that dealer has failed to pinpoint and repair; faulty clutch switch - car wouldn't start; a few sqeaks and ratlles - not what you would expect from germany's finest. What you would expect of a car such as this.

A fantastic car in every way, let down by the dealerships servicing and customer care. The majority of problems were created by incompetent mechanics, who then failed to repair their own faults on subsequent visits

Have had some electrical issues with pcm but mechanically no problems. Tyres are hideously expensive but what do you expect? it's a porsche!

Problem wit gear stick linkage stranded me. About 2 to 3 thousand pounds a year to keep in top condition.

No problems yet. Pricey on fuel but use an independent specialist for servicing so costs are reasonable.

No problems at all. As expected for this class of car but service parts could be cheaper.
