My wife went here by herself to buy a new vehicle ...

My wife went here by herself to buy a new vehicle and applied for financing and was approved for a 5% interest rate at told her she had to pay $3000 down. She looked at several vehicles and ended up bringing one home for 48hrs for an extended test drive, which I will admit was very nice. However, when she decided she didn't want that vehicle and told them she was going to go home and think about it after dropping it off, the sales manager came out and said "oh, well if you decide you want to get it we got you a 1% interest rate", which immediately sparked my curiosity, so I asked "1%? Does she still have to put $3000 down?" and the manager replied "no, no money down and 1%" so I said "did you re-run her for different financing?" and he said no. So I asked "how in the world did you tell her 5% with $3000 down, and now that that we're unsure about buying a vehicle it's magically 1% and nothing down?" The manager did some serious backpeddling and I told him no thanks, we don't want your business and left. We were seriously offended and my wife was very frustrated because she felt like she was taken advantage of because I wasn't there with her from the get-go. Never going back there again and not buying a Mazda.
