He did work for me on a 997. I did have a number of issues with the work some which rendered the car undrivable for a number of days because it would not lock and the dash lit up like a christmas tree. Then the new amp would not work so we changed the headunit at my expense, still same problem, so he came out to my house and tried to fix it but to no avail. Eventually I found the issue myself and fixed it myself (reversed inputs and a bad ground). However he did go out of his way to fix them out of hours and they were fixed albeit the stereo system was never perfect and would take a few minutes to turn on after the car started.
I personally think he is a very nice chap, but always was running late, and underestimating the time jobs would need. When I was around his house, there was streams of fellows turning up with issues needing fixing. Another guy on a Porsche forum rang me saying he was having the same issues, a number of months after I sold my 911, wondering what my experiance was....I think maybe he is not as good on Porsche as BMW. I am surprised at the reviews online. He does sell internationally and I am surprised with what is said. He was very honorable regarding money with me, but it took a lot of time to get sorted and 3 of my weekends were ruined dropping off, picking up and troubleshooting the car. He ripped the leather in the car too, but in the end I gave up.
Still posted my car on the internet mind you http://www.backroads.ie/forums/showt...adunit-upgrade all the pictures are gone missing.
