I'm also looking at importing an e90 M3 like fearjac and have been doing my due diligence on here. There just aren't as many choices north of the border. This thread has some good info but I've got a couple of questions.
What's the green levy excise tax for an e90/e92? Is it $2000 for vehicles that use over 14L/100km but less than 15L/100km? RIV uses a weighted average to calculate fuel consumption. According to natural resouces canada a 2009 e90 uses 15.4L/100km hwy and 9.9L/100km city.
Do you still have to pay the local state sales tax even if you are importing the vehicle to Canada? Does that vary by state?
