Rentals are so neglected its a joke.
Theres a reason why they're dirt cheap.
I'd rather buy used from a dealer, pay a little more knowing how many owners there were.
Think about it, how many people do you think drove for those so called "only a few thousand miles"
You're probably buying into a car that hundreds of people drove and cared less about. http://youtu.be/qmk5W4dura0
