Bought my 2.0 last year for the same reasons as everyone else, liked the looks and refinement compared to the MX5 and wanted economy, though I do now wish i went for a 2.5 just for that extra torque.
Cant say ive been overly pleased with the car though. I bought it at 35k after the previous owner had the rear springs replaced (common problem) - (everything done at BMW in the entire cars history). I thankfully took out a warranty with BMW which has been a godsend!!
Immediate concern was the lumpy idle which is slightly better due to advancing the revs a bit more, but still there which I find incredible given that any other car I have driven idles nice and smooth - surely BMW can build a car that doesnt feel like its going to cut out at idle?
Then at 44k miles the windscreen wiper motor had to be replaced as it wasnt parking the wipers back in the normal position (common fault). Then at 47k miles it had its oil service, and just before this, the emissions light came on.
The light was caused by a split in the exhaust manifold (common problem). During inspection, it was also found to need a new vacuum pump and there was an oil leak so a new gasket seal was needed. Again, all done at BMW under warranty.
The past few weeks the car has been slightly hesistant and yesterday the car died on me on my way to work. No power and needed to be towed to the garage. BMW called me yesterday to say its a fuel injector which needs replacing but cant get the car back until Wednesday (tomorrow) as it has to be ordered in.
So overall, while I like the way the car looks and drives, i'm far from happy with its reliability and shoddy build quality. Especially for what is essentially a low mileage car. There seems to be a lot of common faults with these cars, and a lot of faults with bits breaking/falling off which ive never heard about with other cars, e.g. wing mirror glass, door handles etc.
I'm just waiting now for the roof motor to fail on me, im sure thats in the pipeline just around the corner!!!!! Seriously glad I got the warranty though, the faults so far would have cost me in excess of £2000 to have fixed if I was paying myself.
The warranty is up in November and i'll be getting rid of the car, will be buying Japanese again I think. Pity because I had high expectations of the Z4.
