Based on your post he was saying I am going to !@#$ you and see to it that all dealers in the area also !@#$ you.
Thats a very strange position for someone to take and I think you can use that to your advantage. I would report the individual to the Dealer in writing, just state the facts and let them draw their own conclusion.
I would also report to the BBB.
All he had to say was since we are unfamiliar with the mods we are not comfortable working on the car, please try one of the performance shops.
My car has been modded since it has had 2,500 miles and my dealer has honored my ESP.
Every time I bring it in I say be careful who drives it she has 560 HP. I don't want someone to get hurt. They say we know we only let the SM drive it.
