I think it is easy to get the impression that the overwhelming majority are in garbage condition (poor/fair), but that perspective is skewed by the fact that the ones you are most likely to see are the ones in poor/fair condition.
They are sitting outside the double wide on the state highway on the way to work. They are on autotrader/craigslist because they were neglected and became a money pit. They were some kid's car who has moved on to the next "most illest" ride.
There are also shitloads of them out there that are in very good to excellent, condition, but you wont see them because they are in a garage....obviously being cared for.
I get kick out of C&P posting: "They keep popping up" when the low mile examples do.
Before BaT took off in popularity the past year or so, there seemed to be either a listing here or a post linking to an eBay/autotrader/craigslist listing for what (appeared to be) excellent condition, relatively low (sub-40k) mile specimens seemingly once every few months. It has slowed down lately from what I have seen, but I feel that is because owners have wised up and are either waiting to see how high things go or maybe it has nothing to do with selling but rather they are in better financial shape and are spending more on cars rather than selling and scaling back twin turbo money pits.
Just food for thought
