I'm working on pre-approval from the bank which is essentially the same thing as far as the dealership is concerned.If you walk in with cash, you can make the car saleman sing your tune
The way I did it last time - I went to the lot, found a truck I liked, then I used my spreadsheet to figure out what it costs them, what it will cost me, where the money goes, and how much profit the dealer makes. I present it to them and tell them, 'Accept or Decline'.
They decline - I walk out. Last time I did this I was driving the vehicle home from the 2nd dealer when the 1st called me back to tell me they changed their minds and they would accept my offer.
That said - it's a LOT of work to get a good deal and make sure you're not being screwed most times.
Looking at Ford Trucks at this point - don't really like the way the GM vehicles look [picky, I know]. Haven't looked at Dodge, Nissan, or Toyota yet.I know a couple of salesmen I trust. Will at Bosak Dodge/Jeep and Bruce at Schepel Buick.
