I was totally going to use them to buy a car next month! Are there any good alternatives? I can't handle anymore haggling and tricks.
Zero negotiation, walked in with the paper, that's the price of the car.
I don't think you will get the deal of the century through them, but you'll at least not get screwed. Just don't let the dealership nickel & dime you on protectants & floormats, etc. If they can't honor the exact price, just go somewhere else.
In order to get the best deal, however, you will probably still need to haggle. You can use it as a starting point though.
