I'm cutting my car some slack as for one thing, I love driving it, and from the drivers' position you can just feel the quality; also out here in the UAE it is pretty damn hot, so I would expect the rubber parts to have a shorter-than-average lifespan out here. Other stuff that I have had to replace though seems excessive - obviously all four window lifters failed, a few of the door lock carriers, all corners of the air suspension, all the bushes and usual parts of the front suspension, TWO expansion tanks... doesn't that seem a little excessive in a six year-old car costing 70,000 USD when new? I left a beautiful 9 year-old 323 in the UK with a friend of mine who drove it all round Europe, and has only needed to put tyres on it, in 5 years!
It may be the harsh climate out here, but frankly I'm pretty underwhelmed and out of pocket on my 2006 4.8iS too.
