Mercedes-Benz of Sugar Land

I purchased a vehicle from them on 7/28 and today 8/3 the car is having mechanical problems. I called and they are doing nothing to help me to fix the problem. I do realize that the vehicle was a used vehi car is having mechanical problems. I called and they are doing nothing to help me to fix the problem. I do realize that the vehicle was a used vehicle but I did purchase the car only 6 days ago. And for them to do nothing to help me is very unprofessional. I do not reccommend anyone go to this dealership for a new or used vehicle. More
