I've owned several gray market Japanese vehicles. They are fun, but if you are considering it, budget for repairs and costs to bring them into compliance. I find generally the maintenance is poor - it doesn't make sense to drive used cars in Japan, so owners know they won't be driving them all that long, so maintenance is minimal. Plus a lot of these cars have been sitting around for a long time, which means all fluids have to be changed, and many seals replaced as soon as you start driving them here. It's not a cheap way to get a car, but fun for something different.
