Marcos Maniacs

Hello to everyone. I have recently moved from UK to US, bringing the 
Marcos with me, of course, and now need to have it serviced. If anyone 
knows of a good Volvo mechanic in the lower New York State area 
(Rockland County or somewhere close by) then I would greatly appreciate 
any contact info.
My 1971 car is running well (always having been serviced by Rory, at 
Marcos Heritage) but does need some attention and modifications.
If anyone does know of such an individual or company then perhaps you 
might let me know.
Thanks.
