interesting on that 88 coupe, I thought hicas was only in hatches, guess maybe not in japan...
I've been to japan twice, its been awhile but if you are going 3 weeks and want to go all over the JR tourist rail pass is an option:

I went with a friend so we could split hotel, I could not have afforded it by mself, grab a friend you can trust from here and your golden, flights are actually cheaper from CA, I flew from JFK.
The next time I went was w/ the Dsport Tokyo auto salon tour, it was alot of car stuff which was what I wanted, the first time we just didnt find alot.
Tokyo auto salon was sooo much better then the philly and NYC car shows by me, loved it:
