One of the main reasons for a forum like this is for people to ask about their problems, not to say how much they like the car.
One thing that we don't know is how well the car has been cared for or maintained.
I wouldn't say that these cars are any more trouble prone than many others. There are some things, like any car that will be pretty much a given that you will experience. Intermediate steering shaft clunk, broken rear window regulators, and eventually the front transmission mount. All relatively easy to repair and covered here.
I have no regrets on purchasing mine, and plan on having it for some time. I'm coming up on 90k miles, and have had to replace the intermediate shaft, repair the window regulators, replace a rear wheel hub, replace the rear shock mounts, replace the tie-rod ends, and the front transmission mount.
My friend'* 00 SSEi has had the front hubs replaced, window regulators repaired, power steering pump replaced, intermediate shaft lubed, and a coil pack replaced. Currently, it also has a slight leak in the high pressure hose for the power steering. It'* coming up on 100k.
I don't believe any of this to be unusual maintenance for a 7, almost 8 year old car.
