David Poole is a crook and I woild not believe a thing he says. My 190 was stalling out. I suggested a fuel pump problem. I was told that I knew nothing that fuel pumps on Mercedes seldom if ever went bad. After selling me ignition wires fuel filters battery and several hundred dollars. You got it it was the pumps. David had done other work on my car that failed with the results of 150.00 tow from bf egypt to another shop that resulted in all of his bypassed wiring jobs and other incomplerte work being found to the tune of about 1000.00.Stay away from this guy and his shop European Preformance. And like John Hancock. I have no fear in sigining my name..George R. Chapman Dallas, Texas
