It's not your car until you pay for it (technically). ALWAYS leave a deposit as you can always get that back but once they sell "your" car, you'll never see it again. If you found the exact car you want, you really shouldn't let $800 get in the way. That's a few dinners out with your chick. I held up the purchase of my house for more than a month for a difference of $1,000 but finally realized that I spent over $1,000 in rent just by delaying the process.
