Wells Fargo offers 6.75% loans on new cars. I submitted an online application, got an e-mail approval response in 60 seconds and a phone call within 2 minutes. When your car is ready for pickup, just call your Wells Fargo contact and they will overnight a package with a blank check good for your loan limit and a simple one page form that the dealer fills out and faxes in to Wells Fargo. I bought my wife's Scion xA the same way about 18 months ago. It's easy and quick!
BTW, the Scion xA fully loaded cost $13,500 and gets 38-40 mpg on the Texas (flat) highways. It's our big family car and we love it!
