I purchased a 2007 Toyota Yaris from Merchants in June of 2012, 6 months later I needed wheel bearings and all that goes with them and 2 new tires because the belts were broken on the original ones. 
The local advertising said several things; free Car Fax over 100 point inspection on ALL car and"up to $1500 down and we'll double it". I was fooled: I put $1500 down and was told I didn't qualify for the doubling. I was given a Car Fax report that showed the car had 1 owner, I was impressed. Since I'm not a constant user of Car Fax the free report from Merchants sounded great, looked great. Either they forgot a page or somehow the front end collison the car was in didn't get reported? Hmmm 
The 100 point inspection on all vehicles coming in. Any car failing that inspection they don't sell. They missed a few things on my car! I took the car to a Toyota Dealer; it appears the car had been in a front end collison at one time, not listed on the Car Fax; the front tires had broken belts, Merchants told me they were new, I guess their inspections don't cover tires; front wheel bearings needed replacement, I thought the wear on bearsing would give a good mechanic an idea of time left in service. IF the bearings were worn enough they should be replaced, they missed mine.
I recorded my complaint and copied the bill, sent it to Merchants for review and hope of a chat as to what went wrong and possibly some assistance on the over $700 bill. I didn't and still haven't received a response....their ads continue. Don't be fooled, ask questions and look for proof.
When I went to pick up my car I had to wait over 2 1/2 hours. The slesman was waiting on several people at the same time. I got placed at one seat to another since other sales mane needed the spot. I ended up standing inthe middle of the showroom waiting. If only I was told by the saleman I would not have wasted so much time waiting. I would have made an appointment.
