Mark was supposed to do an engine swap in my car, but had no idea how to do one!!! I had so many problem and I am still dealing with it. He was supposed to be cheaper than anywhere else but he ended up being way more expensive than any other place. I have had to file a complaint with the better business breau to get my car completely fixed because he has stopped answering my calls. Do not go to him for anything! You will regret it.
