Thrifty at DEN
As wierd as it may seem, I've had nothing but good luck with Thrifty at DEN. As a blue chip member, they've treated me very well. The three times I've rented there I was given an upgrade, twice to a Grand Cherokee.
To the poster that was charged $10 for a two door, sadly there is a two door stratus coupe, but the scheme to charge you $10 was a rip off scheme... You should not have had to pay. I would complain to corporate. Usually they'll upgrade you to a full size for less than $10...
