As one of the millions of hurting Americans who are either unemployed or receiving minimum pay, I feel it is my responsibility and civic duty to make all Americans aware of companies to be avoided. On June 29, 2010, this company kept me at their dealership for five hours until they wore me down. They knew that I had lost part of my disability pay and had to trade my new car, a 2010 Chevrolet Malibu LT, VIN# 1G1ZD5EB4AF197734, in on a used car, 2009 Chevrolet Cobalt LT, VIN# 1G1AT58H997268724, to reduce my payments. They first lied to me on the telephone just to get me into their dealership. Once there, they increased the price by $1, 500, but little by little they got within $300 which they asked me to pay. I paid the $300 out of my much needed cash reserve I had for groceries and my required medication just to get the car and get home because I was tired. I am 70 years old and on disability pay. The company also tried to jip me out of the 12 month, 12, 000 mile bumper to bumper warranty. The salesman told me the car was 'Certified' and had the warranty. But, after the deal was verbally agreed upon, the internet used car manager and the used car manager (2 different managers) told me the car was not 'Certified' and had no warranty. They said at the price they sold it to me, that they couldn't afford to give me the warranty. I also asked the used car manager if it had a clean 'Carfax' report and if it had any body damage and he said the 'Carfax' was clean and it had no damage. After signing the papers, I found the bumper on the rear was dented. I failed to catch it on my quick inspection. I am not sure whether the following claim is true, but I deeply believe it to be true. When my daughter and I drove over late the evening before, June 28, 2010, to look at the car, it was raining so my daughter stayed in the car. When I jumped back into my car, I told my daughter that it had leather and new tires. After buying the car the next day, I drove off and the car seemed to noisey and rough. When I got home, and as I was checking the tire pressure, I noticed the tires weren't new. The next two days, June 30 and July 1, 2010, I spent sending messages to the dealer reporting the dented bumper, the old tires, the noisey and rough ride, the car almost stalling at low speeds, numerous spots of paint missing, and the gas mileage not being close to their and GM's claims. I told them the car seemed to have been badly mistreated. The company has a 72 hour, 150 mile window in which to allow you to return the car. In the messages that I sent them, I told them that I preferred to return the car and I asked them to reply. They purposely didn't reply and let the windows expire. And, then they replied and said the windows had expired and there was nothing they could do for me. That was very shrewd of them. I tried very hard to work with this company so that we both could be satisfied with the sale, but making money anyway they can and from anyone they can is more important. Customer satisfaction is not important to them. I would strongly advise anyone wanting to buy a car from an honest and reliable dealer, not to go to Stonebriar Chevrolet in Frisco, Tx. I have bought many, many vehicles from dealers in the DFW area over the last 40 years, and this is only the second one I have found that was dishonest and would not live up to their claims and promises.
