Chris - This is my understanding of the requirements to import a vehicle
less than 25 years old from Canada:

 - Bill of sale
 - Proof of ownership (previous registration/title)
 - Recall statement
 - Certificate of conformity
 - Receipt from a mechanic documenting correction of any exceptions noted on
the certificate of conformity
 - DOT form HS-7
 - US Customs form 3299
 - EPA form 3520-1 (may be required - not sure)

To register legally in my state, in addition to having the forms listed
above stamped by customs, I would need to get a VIN inspection form
completed by the town clerk or a state trooper. In Maine, vehicles older
than 15 years are not required to be titled and no emissions inspections are
performed, but I would suspect other states might have regulations regarding
these items. Definitely check with your state's motor vehicle department to
determine exactly what they will require.
