RON,
As I said in an earlier post, I saved a ton of money by buying an Escalade (demo) at the end of the month. It had 5,000 miles on it and was the dealership owner's car. Perfect condition and already broken in for my towing purposes. Add in 0% financing and all the factory incentives, you can buy a new vehicle for about the same as a preowned. My son just bought a new GMC diesel crew cab for towing. I assume you could get a diesel in a Denali SUV; it might take some looking.
Saw a Ford Excursion w/ diesel yesterday, God it was BIG.
Get your ducks in a row, and then get ready to "Hammer 'Em" the end of the month.
I would think "The TURK" should have some contacts close to you, "who owe him one." Time to call in the chip?
I look at it this way: You are doing the dealership a favor by taking a car off their lot, and off their floor plan. They don't need to make any money off the sale, you have just saved them the interest for another month.
Good Luck,
TL
