I'm laughing at a lot of the stuff posted, but worried as hell about some of the other stuff.
I just got my truck back from the dealership. It went in with a lower engine knock. When it was bought, there was a GMAC warranty available. I said if they got the warranty, I'd take buy the truck. Well, they screwed up and never got the warranty. But I have a 2 year old DUE BILL that says if they can't get the warranty, they would have to unwind the purchase. No expiration, no mileage, etc. So I took it in, they wanted to charge me. Had a guy I ride motorcycles with, an attorney, give them a call. Suddenly they wanted to pay for everything including the first rental car (I rented for a week, they supplied loaner after that) I had. They did the fix (pretty much a lower engine rebuild), replaced the fuel sender unit, tune up, full tank of gas (I figured they'd have to drop the tank and I knew what a hassle that is with about 150 lbs of gasoline so I let it get very low), ran it through smog/emissions, and pretty much detailed the car. Then they also got me a Toyota Care (I knew they couldn't get the GMAC anymore, and it's a Toyota dealer) warranty for 2 years, 24,000 miles. So right now, mine's running pretty well.
I was really considering getting them to unwind the deal, but I do like the truck, and I wanted what was right. I figured if they made it right -fix it and get me a warranty - I'd be happy, and I am.
