FYI....No duty on any car/truck build in North American, so dodge---no duty.....only a $200 RIV fee...that's it. Most states you can get a trip permit-to drive it back and pay your own tax when crossing border.
All Dodge cars are excepted in Canada...no mods needed....possible DRL on some models need to be turned on, all the time. its done by computer, should be free, but some dealers will charge ..under $100 anyway. Car will have to be inspected by Canadian tire...thats included in the $200 RIV fee...then a emissions test here in Ontario you will have to pay for.
As for buying new...it has been done...but Dodge USA dealer are not to sell anything new to a Canadian....used is open game.
According to Dodge.....Car has to be registered to a USA owner first...then can be sold to a Canadian. Don't matter if its new, 2 months old or 10 years old.....it can still cross the border and be registered in Canada.
If for some reason you can get a Dodge dealer to sell you a new one.....it can be brought over the border and registered in Canada..age don"t matter.
Don"t forget thou...Dodge Canada and Dodge USA will void your warranty on both sides.
Some manufactures .....like GM will warranty a car in Canada after it has 12,000 km on it and been in service for 6 months or more in the USA.
Many others don't care...like Toyota....warranty is valid from day one.
I have imported before..back in 2010, I don't think much has changed.
