You can give Rick Anthony a try. He is a terrific mechanic that has done great work on my corvettes in the past and is located out in Downers Grove. He can do the work right in his garage so his overhead is kept down to a minimum. Straight shooter and well trusted throughout the Corvette community.
I am not sure how many foreign cars he has worked on, but I am sure he can do it as he as been a mechanic for quite some time. Shoot him a note and see what he says.
I know I have his number here somewhere but I cant find it at the moment.
Or you can always catch him on the Corvette Forum in the Midwest section and his name there is VetteTech81.
