a little pain for lots of fun gain
 In the market for a car in 2009 and for the price of a boring Accord V6 ($39k in Canada) I got a 530xiT CPO with 60,000 km on it.Had to deal with electronic glitches here and there (tire sensors, oil level sensors, etc) and the transmission is somehow brutal when accelerating from a red light.Also experience problems at idle, irregular rpms..but all covered by CPO warranty.Driving is a blast: I put 40,000 km on it annually and wouldn't want to drive any other car @$700/month. If I could afford a '12 MB E350 4matic station, I could consider a trade but even if I need to rebuild the tranny, it will still be cheaper and more fun to drive my 530xit into the ground.170k km heading for 400k
