I guess I should tell my tale of trying to import a Canadian car.
Started in Jan. '06. I have a '90 NA Jetta and wanted a TD. Everywhere I asked (except US Customs) said that a Canadian car was easy. VW, when asked would provide the appropriate letter of conformance.
So I bought a car in Toronto, took the pickup and a car hauler (from NC) and picked it up in May '06.
Getting the car into the states was easy. Now trying to get a title was something different.
When I called VW North America (I called several times trying to get a different answer, tried a letter as well(no response to that)) they responded that they had a policy change. They no longer provide statements of conformance to import Canadian cars into the US as of March 2006.
The US importation website says that without a statement of conformance all imported cars must be upgraded to the 1996 standard if manufactured before 1996. This means: drivers side airbags, CAT (even on diesels), that terrible passive restraint system that VW US cars have during that time frame, US spec. bumpers and do an Emissions test (yes even diesels) on the engine. And all the work must be done by a Registered Importer. I contacted two RI's and they wanted $6000 for that work.
Bottom line, my Canadian car is a parts car now.
You may be able to find a way around the red tape, but I never did.
