Dave: Massachusetts doesn't give a rat's pitootie about where a car comes from. And they automatically assume that it is a polluter if you ask for an emissions waiver (They also assume that it was made from stolen car parts, but that's another story).
The only thing they seem to care about is not increasing the carbon output by one more old, polluting car on our roads, so if you want to register a relatively new "special interest" car here that replicates an original, you must first buy a pre-1975 running (and recently registered) car of the same or larger displacement, get it crushed for the salvage title as proof that it's gone, then apply that salvage title to the new(er) car for an emissions exemption.
As you can imagine, several people are now scooping up all of the registered pre-'74's they can find and are asking north of $3 grand for them. Work is afoot to change this rediculous law, but the wheels of change in Massachusetts turn ever slowly (except when they voted this stupid law in after midnight when they had a quorum +2 legislators).
I don't blame Chris for taking his route - It makes a lot of sense.
