I moved back to Canada and brought my US car (Audi) last year, what a mistake.  I did all the work  myself, but used a broker to help with the US paperwork.  The import duties, tax, charges, etc etc etc from Canada were very high.  Then when I got it evaluated as a trade-in this year the Canadian dealers treated it like it had Ebola - the speedometer, etc.  No one cares that it has not seen salt and Canadian winters and was well maintained. 
 Unless the car is a rare find at a good price, don't import it.
