While more of an expert in snark, here is a recent account of someone importing an R32:

This is the company he used. They seem to be the go-to importers at the moment, and keep an inventory on-hand. If nothing else, this should give you an idea of prices you can expect to pay:

I know this guy personally, and have for many years. He charges a flat-fee for import expense and you pay whatever the car goes for at auction. It is a bit risky since you can't investigate the car in-person, but you also know exactly what you're paying for. If nothing else, he is a great source of information:

Other points to consider:
- Many insurance companies won't insure the car, and especially not for whatever you're going to pay for it. Expect to have to go through a collector insurance company, which often comes with annual mile limitations and is generally more expensive.
- Don't expect a bank to finance you. At least for now, many banks have no way of properly assessing the value of these cars. Getting a loan can be difficult to impossible.
- If you buy from another importer, make sure the car is titled. The two importers I linked will take care of that for you. If it isn't done, the process can be very time consuming if you're not experienced in it, and cost quite a bit of money. (I can probably get the exact cost if you want, but don't buy an imported car without a title)
Edit: This is more for importing any car as opposed to just an R32, but hope it helps anyway...
