Limo prices - please give me your opinion!

I was quoted the following for limos, does it sounds reasonable to you??? I am petrified of being ripped off and I think that this will barely be enough for me timewise.

Antique Bentley for 3 hours $475
12 person Jaguar for 5 hours $750
10 person Stretch for 3 hours $400

good, those prices sound about right & it's one more thing you can cross off the list
