I took a look at http://www.zipzoomauto.com/

Nice work. One thing I dislike is the absence of PRICE until I fill out all the information. A lot of online fads ask for all your information (including credit cards) before they tell you how much they are going to charge. And this is really a bad practice. Just tell me upfront how much you want me to pay before you ask for my email/phone/name/address etc.
