I had a bad experience with a similar service. It led me to a dealership which claimed to have the car I wanted at a < MSRP price. I called the dealership ahead of time and they confirmed they had that car at that price. I got there and oops they forgot to mention that the car had a extra options package that increased the price by $$ also the car, in our opinion, had a manufacture defect which they said was normal. Finally they gave an offer on my trade-in that was about half the bluebook value. Almost on a whim we we stopped at another dealership on our way home and got the same car, sans defect, at a lower price with a higher trade in. I think the dealerships that participate in these services rely on customer trust. The customer wants to believe they are getting the best price and the customer doesn't want to comparison shop, they just want to buy a car and go home. The participating dealership is taking advantage of that. We stumbled upon a effective car-buying technique - come in the dealership late afternoon and tell them, truthfully, that you've got to get home before the baby-sitter leaves in about 45 minutes. We were just planning to test drive but they were motivated. "We want car for X", "You can have it for Y" "We don't have time to bargain we've got to get home" "OK, you have have it for X" We got the car we wanted, the trade-in value we wanted, we brushed aside all discussions of extra features. Gotta go, take it or leave it. We made it home in time and she did really have to leave. We're not good actors, I think we could only get away with it because we were 100% sincere
