Canadian car okay to import to US?

If I recall the process is much easier when the car is 25 years or older, there is a dealer on this forum who has a lot of experience with this that you could hire to handle the transaction.

 

I've imported a Canada car to the US. There are a few major potential obstacles you need to be aware of:

1. The car has to pass US regulations. Luckily, Canada and US should share most regulations, but there is the chance you might be required to modify your Canadian car before you can register it in the US. The speedometer is a common one since Canada uses km while US uses miles. HOWEVER, the inspection for this is often highly subjective to the opinion of the CBP officer. Sometimes they don't even bother to look at the car beyond the VIN number. Furthermore, I think most officers don't care about the speedometer.
2. Import duties will be 2.5%, which isn't so bad. However, the big one is registration taxes. Depending on the state and how long you've owned the car, it's possible that the state will demand you to pay full sales/use tax on the vehicle. I can't remember if Canadian regulation forces you to pay Canadian sales tax if you are an out-of province buyer, but if you do, then you could get taxed twice!
3. Finally, warranty. Double check with Ferrari (or whatever manufacturer the car belongs to) to see if importing from Canada to US voids the warranty. For example, for Mercedes, it is fine, but for Hyundai, the warranty gets voided.

 

the import duty for US is a one time charge... check to see if car was originally in the US before finding it's way to Canada where import duty would have been initially collected as part of the sale... would be exempt from a double dip by US

Canada should not be collecting any local taxes as part of the sale, such as a sales tax on car for export, it's the same as sales between states, generally solved with affidavit stating destination of use is out local jurisdiction / export, taxes will be collected by new "home" state of residence. In the case of double dipping on both ends, one of the taxes are generally recovered, best to settle before paying as recovery can get messy
