I have a 2008 BMW 550i with 40K miles on it. I have zero problems with it. I have only changed the oil and replaced the battery twice. Runs like a top. Will change radiator fluid soon. Runs as good as new.

I have owned all sorts of luxury vehicles in my life, and I am not a young chicken! This car drives like a luxury sedan. Even better. Its' big, comfortable, fast, gets good gas mileage and performs better than any other car I've owned. The problem is they no longer make it! Big problem for BMW. You can get one in Europe. In fact, you see them all over the European countryside.

I seem to have gotten the opposite of lemon. Got the car as a CPO and drive it about 15k miles a year combined city and hwy driving. I have done zero maintenance other than brakes (once), tires (three t8es) and oil changes (every 10k miles). The only caveat is this car will chew through tires - you'll get about 30k out of a set no matter what you buy - and because of the AWD, you have to replace all 4 at once. It drives like a dream - especially on the back roads. After a snowstorm once the seal around the rear window got dislodged and water got in the trunk and down into the well under the spare. BMW stupidly put some electronics there and the TPM monitor control until got wet and shorted out. I dug it out of there, dried it off and let it et in a bag of rice of for a day or two. plugged it back in and it worked fine.
