Auffenberg Mazda

my son (21) was forced off the road and rolled his first mazda 6 about 2 months after he got it. great car!! air bags saved him. well, he wanted to get an identical car, got pre-approved and found one at auffenburg, ofallon on their website. same price as the first, etc. he was excited. we went there early sat. morning and couldnt find it. sales guy comes out (nice guy) and said, oh, yeah, sometimes it takes a while for the website inventory to catch up. no big deal. mazda dealers in St. Louis had a couple of what he wanted. we'd just have to bite the bullet and go across the river, which would make for a very long day. however, auffenburg DID have one there, identical to what we wanted but it had a $2k tech package, totalling 22k. so, i said to the sales guy, look, we're going to buy a mazda 6 today, he's been pre-approved. it's going to happen, so, you sell us that car for 20k and we'll buy it right now. he's pre approved, i'm co-signing and everything will be cool. he goes and talks to his manager and comes back and says, its a deal, he'll do it. he sits us in his office and leaves then comes back and says, oh, he cant give it to me for that price, says that car is sold. oh really? too bad, we really wanted that car. so the sales guy leaves and comes back. ok, he'll make you a deal but cant take the $2k off, only $500. i said, buddy, this is a classic bait and switch!!! i want THAT car for $20k. THAT'S the deal that got me to sit down in here in the first place. he leaves - again! - and comes back with the manager who hands me the "dealer invoice" which, I think, was just some official looking word print out that shows he's only going to make $500 on the car if he sells it at sticker. i said, look, you told me $20k for that car. it's got the tech pkg we didnt really want. he goes, oh, well, i can have you the exact same car here this afternoon without the tech package for $20k. i said, yeah, i bet you can, but i'll go across the river and buy the same darn car from somebody else and not from you just on principle!!! you tried to bait and switch me and now you're trying to get me to buy a different car from you? not going to happen, pal. last chance: $20k for that car out there or i walk out of here and buy one in missouri. then he said, well, i'd hate to see you do that.... so he cut the deal. we ended up with a mazda repeat buyer deal (500 or 1000 off - i forget.) and 0% mazda financing. it was a pretty good deal, but GOOD GOLLY!!! why do these guys have to do things like that?!!! bait and switch and then argue. jeez! i'd almost rather take a beating than go buy a car! i guess its like that where ever you buy a car - you have got to be willing to walk away and say adios. oh and i've seen recommendations that say to shop around...that's good to do but dont let them do a credit check on you. everytime they do, it drops your score a little bit. and by the time you're at the 3rd or 4th dealer, they're saying, boy you HAVE been shopping around!
