Thats literally the last place I'd suggest buying a car from, 99% of them have been mistreated to the highest extent (just think back to how you treat rental cars lol) my bet would be on the whole car falling apart as you drove it off the lot.
One way you could find some cars to look at is to go on some car buying websites, you could try searching cars.com. autotrader.com and craigslist.org, those'll probably give you some good cars to look at.
