getting a good deal

i haven't paid more than 80% of the asking price for any car i've bought in the last decade, i use this as a rule now

don't look to keen.

don't keep going back to look at the same car (it's like blood in the water with sharks)

be prepared to make your offer in writting then and there (do not make verbal offers)

put every last little thing you want them to do as a condition on the written offer (remember this is a contract)

don't go looking at cars with chicks, sales guys become even bigger tools when chicks are present
