Bought a used car

Bought a used car from Abe and it was the worst decision I've ever made. When I purchased it there was a coolant leak which he said was just a hose that needed to be tightened and that he would fix it...he never did. The car kept overheating and leaking coolant. Had it checked out by Goodyear and they thought that it might be the head gaskets leaking. I told Abe about it and he assured me that it wasn't the head gaskets, but some other problem. Well after he "fixed" it again the car kept acting in the same way so I took it to Ralph Schomp Honda to get a diagnostic and lo and behold, it was the head gaskets. Somehow the car passed emissions, but this is not a mechanic I would ever use for anything. He advertised the car had 70000 miles on it but after I purchased it I had come to find out that the car really had an unknown mileage because he had replaced the cluster and didn't inform me of this. This guy is a down right crook and nobody should be trusting him with their cars. He never does what he says he is going to do, and is very shady and shouldn't be trusted.
