2008 BMW 5 Series Sedan 528xi 4dr Sedan AWD (3.0L 6cyl 6M)
No issues . . . maybe I'm lucky?
 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.
