This subject has been discussed many times. You can buy an ML in the USA but you have to have the registration in hand when you bring it into Canada along with your PAL. I bought mine and then the dealer stored it for me until I had the paperwork done. You will need the usual stuff....make, model, caliber, barrel length, serial number. On the return trip the Canadian Customs will take the HST. Good luck as there is a great selection and they are less $$$$ over there. Many Canadians want to be patriotic and buy here. Nothing wrong with that either.
