Hey Kuan,
Nice... I missed that one. We were driving by on Christmas Eve night, coming back from Kenwood where my aunt lives...
I'll have to stop by next time I'm in town, -- this summer?
Regarding shops in Mpls, there's that outfit on Exclesior Blvd. on the right side as you head towards the lakes. "German ********", (??) or something to that effect, don't recall the name. I always saw Audis in the lot, not too many MBs. Perhaps Deeph8 can look into that one.
When I lived in Mpls and had a Saab 900 I took my car to a group of great mechanics, they worked on some pretty nice cars: Ferraris, RRs, MBs, Porsches you name it. My Dad took his cars there for many years -- Located in a St. Louis Park, kind of hard to find. I'll do some searching and get the name for Deeph8!
