Gillman Mitsubishi San Antonio

I bought a used car from this dealer. When I check car, I found that the battery for this car is changed but not reported on CARFAX. The sales man said that's a new battery. But just several days later, I can't start the engine because the battery didn't work. I had to call roadside assistance. I came to Firestone, they checked that the battery can't work normally, and also there is tire wear, and recommend to do tire alignment. The salesman told me that they had done mechanical inspection before they sale this car. They did nothing on it. I did not recommend to buy a used car from this dealer.
