Acura of Dayton

I recently bought a car here from their used car lot, and I am really disappointed with the service. We bought a used Acura MDX which was supposedly Certified. There is nothing certified about the car. I have had it less than 2 weeks and I am already having problems with the vehicle. It was also supposed to come with 3 months of XM for free, and it was turned off after a week. Their customer service is horrible, they lost some account information of mine, not telling me until a week later. After they sell you a car it seems like they want to have nothing more to do with you. They are the only Acura dealership in Dayton so this is why we came here. Next time I will definitely be looking in either Cincinnati or Columbus.
