Any one out there from massachusetts? How did you register yours? I thought about antique plates but there are alot of restrictions.Don't know how well they are inforced. commercial plates will cost a fortune here with insurance. I don't know if I have to go with commercial plates due to weight the tag says 20,000 lbs.I am only using it for personal use. Most people around here don't even know what a C50 is. I haven't talked to my insurance agent yet but I have 4 cars with him now so he will have to get inventive or I'll be shopping for new insurance for all of them.
