Just use a site like true car or cars direct to get a reasonable ball park price. Then see how far down the dealer is willing to go. Then just make sure when you are in the finance office to say no to everything.
Thanks for the advice. I ran a true car quote this morning on an SR5 premium with a moonroof. MSRP was $40,079 and true car came in at $38,172. This is in central Ohio. The price seems terrible compared to what others are saying they've been offered. I was scanning through last year and saw people saying they were getting these in the $33's.
