I want to express my disappointment with this company I bought a uses 2012 Toyota Camry from them and everything was good until 5 months later. I was feeling my cars transmission slipping, then I took it to several mechanics and realized that the cars transmission was bad. I reached out to DCH about 5 times and talked to management, but they never returned my call. I even tried reaching out to the salesman and he never called me back. I did speak with the manager one time and he told me that he'd call me back and was going to get someone to try to fix the transmission. Guess what I never got a return call ever from these people. I spent about 11K on this used car and I didn't purchase warranty because it didn't make sense to purchase it at the time, but I later realize that these people are the definition of c used car sales dealership. They don't care about customer service. They only care about making the sale and making money on you. Don't buy cars from these people. Be warned people.
