NONE, get 'em in the price. But be ready with loan information before you get there. Be prepared to walk out. Car dealers are pretty bogus. Before you go, check them out at the Better Business Bureau
http://www.bbb.orgI found out later that the last dealer that I worked with had 2 outstanding complaints. In this economy, a car dealer is dying to get your business. So show them that you mean business. A dealer across the street did not even bother to respond to the complaint. Just up the road, another dealer has complaints showing. The dealer up the other way, also has outstanding complaints. Another dealer about a mile away hit the JACKPOT with 4 complaints. So bring a printout of their complaints at the BBB website and scare them into more discounts. The lower the price, the smaller the loan.
