I picked up my 89 535i for 6400 w/tax. It needed rotors up front. So figure another 200 bucks for some nice ones so i was up to about 6600 total. The BMW mechanics said the cars engine was and is in great shape. I have 130k on it and they predict with proper mainenece I will be getting above 200k. now the adition of my turbo may creat a little bit extra wear. Overall my gass milage is about 20mpg so thats great in my book. The BMW computer seams to be a bit optimistic on mileage but still kinda close. thats just my 2 cents. If you want a nice nice car check out a 89 325is or a 88 535is both nice rides. thanx, josh
