Stokes Mazda

Yesterday my husband and I went to this dealership to get a Mazda3. I told the man exactly what I wanted and he told me the trim I should get would be the Grand Touring. First off I loved the car. He was right it had everything I wanted. So after we drove the car we told them what we wanted to pay and he came back and told us that what we wanted to pay would be fine and everything was going to work out. We had to go to our bank to get the loan but the bank was closed. So they gave us the keys and said just to get it down tomorrow and bring the car back to get it detailed and the tank filled up once we got the loan. So I was driving the car all that night and today. When we went to get the loan they pointed out the VIN number on the sheet didn't match the car. They didn't make a big deal about it. Just used to VIN on the car to secure the loan. So we got the loan and the check and went driving back to the Mazda dealership to pay them and get my new car cleaned up. Before I handed them the check I casually said something about about the VIN's not being the same, thinking it was just some silly mistake. The financier looks at me confused and says that the VINS wouldn't match because that wasn't my car. Of course I'm confused and told him so. Apparently without telling us they decided if we wanted to pay a certain amount per month that we had to get a lesser model. NO one told us this. We both were under the impression that we were getting the car we drove off the lot with! When we said as much all they had to say was we're sorry for the misunderstanding. Do you want the lesser model? Of course we said no. At this point just on Principal of the matter. My husband even tried talking to the manager who took a phone call from his PERSONAL phone in the middle of my husband talking! The salesman also told us that he informed us of the change, which he certainly didn't. Why would I take home one model but be getting another? That just doesn't make any sense! What makes it all worse to us is how much they thanked my husband for serving in the military and how they respected him so much and how gratefully they were to him and they they tried to rip us off!
