Thank you Croc,
I spent a lot of time digging in to the new (4/30/2012) MA laws, believe I know more than most, am aware of the links you provided, (and many more). I have been in contact with Aidenparte, his car is titled as a "Lotus" (and imported) was done before the new law deadline,( but still should have met the new law) I'm sure the RMV is clueless in practice.
I was very worried about buying a car and not being able to register. I am confident it can be done, but confusion reins throughout the system, I suspect for a while there will be little consistency in it's application and I may be the first Caterham.
