Okay, you can see the dates and the auctions. two are average, meaning whomever bought them has to spend money on reconditioning, oil change, inspection, detail, tires maybe, and anything else that is wrong. Below average means it is a turd bucket and a NEW car dealer wouldn't have bought it, or it was bought by a low end used car dealer. Go to Craigslist in your city, and search under "for sale by owner" and you will get a prety good idea what your is worth if you sell it yourself. be honest with yourself on the BMW's condition and it will save some headaches. Everybody should have the joy of selling their car out of your driveway!
Ask away if you have any more questions
