I've been looking through a ton of Carfax reports while looking for a used M3. Question is simple - how big of a red flag is it when a car has been to an auction? With a car as "rare" as an M3, I would think dealers would want to resell any and all halfway decent M3s that come off lease, are traded in, etc.
I've also found that many of these auctioned cars end up at non-BMW dealerships, have otherwise clean histories (according to Carfax at least
) but are selling at $2-4k discounts over similar cars found at BMW dealerships. Are these types of cars even worth checking out or is that taking too big of a chance?
