Damn, I drive what some of you would consider a rental car as my daily driver.
I haven't had any unusual loaners, though. Never had a loaner with this one because nothing's gone wrong that's required it to go to the shop yet. When I had the Contour, I got a silver loaner Taurus and couldn't stand how big it was at the time (imagine that, driving a minivan now). I also had a loaner Focus hatch, and I thought it was a cool little car. I liked how you could play the radio without having the keys in the ignition, but the lack of power anything or good cupholders (but it had foglights!) was a turn off. If I got one, it'd have to be better equipped.
