+1.
I've also seen a large quantity of rusty ones out there.
When I get a chance later tonight, I'll show you the underbody of a fresh import BB R34 that I saw shortly after I bought mine. You'll love it.
R34 are commonly prone to rust around the rear boot brake light, I've also seen rust around the strut tower welds, window seals etc.
I believe the original Japanese location of the car will obviously also play a significant part to how exposed it was to salt.
Good thread, however maybe should be split in two parts and the bulk moved to the general discussion area and the other moved to WTB?
