First of all, great car.
Anything 25 yrs old and in stock configuration is 49 state legal. Stock config is key; no engine swaps, old VIN's on a newer chassis, etc. Customs is sensitive to this and are fairly well educated on the popular vehicles being imported, but they are professional and reasonable. You may have some work to get it titled and registered, many state RMV's just aren't familiar with non conforming VIN's, but you will get it done. Insurance can be a challenge, but the collector car companies are always there.
Importing one yourself is not that hard, you just have to learn the process, the requirements, line up carriers, and you may need a Customs Broker. If the vehicle is dirty say w/ caked mud, there will be a mandatory steam wash, which you will be billed for. There are a lot of write ups on the 'web, and I would talk to someone who has done it. That said, the reputable importers have plenty of landed cars here. Unless you really want the sense of accomplishment, I'd buy one landed or have one imported for you.
My situation got twisted a bit; I lined up all of the above and went looking for diesel Defenders, then got promoted to Compliance Officer which included global import/export compliance. I quickly decided that I did not want my silly car hobby potentially putting me on CBP's radar screen and impacting the corporation.....I found one that had just arrived here.
PM w/ any questions. Glad to help.
