I rent cars pretty regularly, normally for my business trips. It's a great way to check out a car you might be considering in the future.
I just turned in a Fiat 500. Rented while my own vehicle was down for maintenance.
All I can say about that car, for me anyway, is I hope I never have to drive one, or ride in one again.
I did not like it.
Only other vehicle I can remember disliking that much was a Dodge Nitro.
To each his own, but now I have two vehicles to avoid.
