Lots of great things to think about. We haven't looked at any other cars at this point, but I have a coupon to get a $50 American Express Gift Card if I test drive a Hyundai, so I'll check 'em out. Now, my mechanic had told us to stay away from Hyundai and Kia, but Inadvertent Imitation, it sounds like you've had good luck with yours so I'll definitely pay closer attention.
Infamy Of Crete, I haven't looked at the Honda Civic in person, but it didn't get as high a ratings from the various car reviewers (Edmunds, Consumer Report, etc.), so that's why I picked the Prius. Maybe I should take a closer look at the Civic.
Thanks again, everyone! We still haven't made a decision yet.....
