Frank, I think that title you have is probably pretty rare. They haven't titled pre-73(?) (I think '73 is the cutoff) cars for many years in CT.
Also...my 2 cents on the property tax thing...Property tax on vehicles/boats/RV's in CT is paid to the municipality where you live...no direct affiliation with the DMV. The municipality does the recordkeeping and billing for this...which you can imagine is not perfect. On more than one occasion, I've received tax bills for vehicles that I have sold. In those instances, I bring the bill of sale and the tax receivable is cancelled. I could just as easily have paid the bill and they would continue to bill me. It would not prove anything about me owning the vehicle. It would just prove that I'm stupid.
