Kinda answered your own question hehe, but I’ll elaborate. Day to day stuff consist of repair work on older and newer European makes (everything you named and then some). Between the shop floor and the 2nd level storage I honestly would have to say MG’s probably out number everything else, with Hondas maybe being a close 2nd. American cars pass though there a bit also, right now over in the one corner I know there is a viper with a blown engine. And of course all the usual assortment of ricer burners.
I suppose locally the thing they are known for is having the most customers in club racing and autox (SCCA, NASA, etc). They have built many full blown race cars (a few Domination put cages in). And maintained several cars that My car is currently down there in the back so I can work on it. They are also pretty heavily involved with the Pittsburgh Vintage Gran Prix.
