Maybe I missed it, but I see all this info on the car but I don't see 2 major details. Is it a GSR w/ the original b18c1 in it? If so, how many miles are on both the motor & chassis? If it's not the original motor, what is it and how many miles are on it?

I'm still kinda drunk from lastnight so it's possiblei just skimmed right over those details but I couldn't find'em.
