Audi Nashville

I purchased a 2016 Mercedes GLA 250 from Audi Nashville. The car was in excellent condition and had 47k miles. It was advertised on the 3rd party site as a flex fuel. Although I had not owned or operated a flex fuel vehicle, I did some research, including looking at Mercedes site that claimed their flex fuel vehicles were designed to run on either premium or E85.  Please continue reading thru this so you can be forewarned of a totally dishonest dealership. I know, imagine that with car dealers, right? I asked the sales rep Joe V. about his experience with high end brands running on E85,if they had any problems along with several other related questions. I explained to him I had not had flex fuel before so I just wanted to know.  A month later and 2k miles, the engine started suddenly misfiring badly. After getting it into Mercedes dealership where I live in Arkansas it was discovered this was not a flex fuel vehicle. My repair was 4300 for replacement of fuel injectors, plugs, oil change, reprogramming etc.  I discussed case with GM Robert H at Audi Nashville, who denied that his sales rep ever discussed this car being a flex fuel. I am certain they changed the details before sending the archived ad on the vehicle. If I did not live out of state I would have an attorney look at this but it does boil down to he said- he said so I know how that turns out.  All I was asking in the end was for them to own up to misrepresenting something so crucial to the car and split the repair with me. Even took it to the corporate level of Sonic Automotive to no avail.  I will never trust anyone associated with Sonic Automotive or Audi Nashville and I recommend strongly you do not either.
