On the other hand, we had an ex-Enterprise car that was fine. Had 30k miles on it when purchased and 90k or so when we sold it a few years later, not because of anything wrong but because we downsized to one car (and the other one was worth less $$ to others but perfectly fine to us). Never had any serious problem that I can remember. Was a Mitsubishi Galant, 2003. There was admittedly a family of employee discount involved in the purchase that made the price that much lower.

So I wouldn't rent from them but wouldn't rule out buying from them.
