Thrifty...Too Good To Be True?

[Kevenswife2]

Thrifty car rental just gave me a great rate for my 9 day rental starting Thanksgiving day. Is there a reason why their rates are so much lower than everyone else? Do they 'tack on' unexpected charges when you pick up the car? Are their cars in good shape and newer models?

I guess the price has me 'wondering' and I'd like some reassurance it's 'okay'.
