I thought about whether or not to identify the owner, but he has his business name on the car so I'm guessing he would like the advertising.

It belongs to Matt Blast, owner of Eurometrix http://www.eurometrix.ws/ Matt is the guy you go to to have your Porsche's carburetors or throttle bodies overhauled.

I understand the car was raced by Danny Ongias during its original racing career, but I don't recall other details.
