A good friend of mine had an 02 and now as an 05 SE-R spec V. The 02 had a recall on the engine (his wasn't replaced but a lot were) and the engine in his 05 crapped out with like 8k on it. They are decent enough cars but I wouldn't buy one as I don't think they are the same level of quality you used to get in Nissans. My buddy has been lucky and leased his.
Do you have to buy a US spec car? I was looking at the military mart's website and they have a real nice looking Audi S8 for $19,995

It won't be the cheapest thing out there to maintain and repair but it sure is hawt
