I've recently had a bad experience with a company, which more so made me mad over anything else. So I'm gonna be that person that writes a bad review for all my friends and family to see. So this place, Super Auto Company off of Sheridan and Colfax screwed us over. My dad and I went in last night to see about getting me a newer car. My dad wanted to trade my car in for a few grand and put that towards the car he was going to get there. Told the salesmen and he approved. I got approved for a car and we went and looked and I picked one. It was a Buick. Well we ran all the numbers and whatnot. The bank wanted $1,500 down and I only had $500 cash right then and there. So we asked if it would be possible to pay $500 now and hold the car and sign an agreement and pay the rest in a couple weeks, as my dad had previously been told by them could happen. They said they'd need to ask their manager and see what he said about it because he usually likes more down. So he said we would sign all the papers and get everything ready so we could just take the car home tomorrow (tonight) without issue as long as the manager okayed it. He said he'd take the car off the market. It was ours. He said he'd text both my dad and I at 1:30 today with the answer. I waited until 3 and called and apparently the salesman was off today. He said he'd try to reach him and have the salesman call me tomorrow if he couldn't reach him. Well my dad went in after work and found out they weren't going to give us enough for the trade in and asked for the money we put down ($400) back and no deal. The guy told him no, that since he took the car off the market they had all rights to deny the "refund". Well my mom and dad went in there tonight to get that back because I didn't get to take the car home. I never even got to test drive it and the guy never got back to me on whether or not the manager okayed this plan. He acted condescending toward my mom and treated my dad like crap. But we got the money back. But if my mom had not gone in there, we'd be out $400 for trying to buy a car from someone who just screwed us over. That's all. Screw you Super Auto Company.
