TPWS
I went by TPWS in the fall 2008 and talked to one of their Techs, I forget his name, but he was very friendly. They showed me around the shop and the various projects they work on. I personally have a 944/968 background and their knowledge and williness to understand the economics of such cars was very inviting. I hope to go by soon and get some photos:
