I owned a 2003 BMW 325i and it had plenty of problems in the 2 years of ownership. It was the South Africa build so I'm not sure if the place of assembly had anything to do with it, but either way reliability was iffy. It got outstanding gas mileage, was great on road trips, and was super fun to drive.
My left rear tire blew while driving and when I took it off I noticed it was rubbing against the wheel well and had worn down the tire to the point it would blow...not good.

I took my car in because the service light kept coming on, staying on, then turning back off and then the car would just not move or move slowly. BMW kept the car for over a week because they needed to replace valves and a head gasket (I believe, it was years ago) and it was pretty ridiculous for a car that was 1 year old at the time.
At any rate, BMW service is great, but the cars are kind of hit and miss.
