The sixth step of the car buying guide is a fun one. Figuring out how much the dealer owns their cars for...
New cars are much easier to figure and finding the invoice is simple. Use either one of the car buying websites mentioned above, Yahoo! Autos or CarsDirect, and you'll quickly find MSRP, invoice and be able to get competing quotes.
Figuring a used cars cost is quite a bit different. The easiest way to do this, but not necessarily the most accurate way, is to get the trade in values from either Kelley Blue Book and/or NADA.
Take those trade in values and figure about $400 - $800 (reconditioning cost) on top of those figures to get a rough estimate of what a dealer owns a used car for.
