Best service i ever had was in Lansing, MI, with my Merkur Xr4Ti,,,the guys knew me and the previous owner, and did everything and more right the first time...they treated that car as if I was bringing in a Ferrari. The owner used to race them in that series that used to race before the Indy care in street or road courses.
The VW guys had an atrocious time getting to fix my Scirocco 16V. They werent very good.The Ford guys..I dunno,,you could throw a grenade in the engine bay and getter better results!
