Found this out front of a dealership on my way hope from work. A few days later it was my daily driver. Over 175k miles on the odometer with little to no problems at all. The car has been lightly modified and well maintained.

This is not the type of car you buy and expect to be maintained by your local BMW dealer. The costs for doing so would be insanely high and would surpass the value of the car almost instantly. Instead, be prepared to do lots of work yourself or have a good independent mechanic available. Parts are becoming harder and harder to source with many being NLA (no longer available) directly from BMW. There is a very small aftermarket offering for these vehicles as well.

They are fairly complex cars which seem to have just about two of every component (batteries, fuel pumps, intake manifolds, etc). That being said, a well taken care of example will probably only need minor maintenance from time to time. Its not uncommon to see these cars with 150k-300k miles on the odometer.

In stock form, they aren't overly exciting to drive. Electronic tuning and suspension upgrades are highly recommended at a minimum to wake the car up. A supercharger or twin-turbo system turns a fairly slow car into an absolute rocket ship.

They are comfortable to drive and pretty reliable. Be prepared to receive lots of thumbs up and looks as you drive through town as its certainly a head turner.
