i'm purchasing a newer used truck soon, within the week probably. I want to be able to drive off in my new truck having spent the least amount as possible is the goal. what i've already done - -- been to the dealer, met with a salesman -- talked trucks, did not talk money except for he asked if i was financing or trading in (no to either) -- decided on a truck that I want (2008 Ford F150 XLT 4x4), salesman knows this. priced at 22xxx sticker. I've asked if there are any incentives/rebates etc, already down to 21xxx without me really trying -- i've seen this truck on the lot for about 2 weeks now prior to me stepping foot onto the lot I've got my loan set through my credit union, so I will not be financing through the dealer. I think my personal price point I'd like to see is somewhere real close to the 20k final cost (including title/registration/bs stuff) mark. I've read about dealer invoice and markup and what not, but I have no clue in the dealer world. I've always purchased privately, this will be my first experience with a dealer. I've got a free weekend (not buying this weekend) and I was thinking of going to the other Ford dealers to get an idea of what they would do price wise. I like this salesman (of course that's their job...) and would like to give him my sale but I also want a price i like. so... wise people of OR - what did i already do wrong, what do i do from here to get close to that 20k mark?
