I agree, the first one is the better of the two IMO. I prefer buying older vehicles privately. I have nothing against dealers, my family actually owns a dealership. But when a dealer sends a car out for inspection, if it needs a tire, it only gets a tire. If it needs a shock, it gets a shock.
As cars get older, the private owners tend to take care of them and thus, they're still good vehicles. The ones that don't are the ones that they usually dump off as a trade in. How many people have you heard tell a story where they think they got over on a dealer trading it a POS?
