Its same here and even in US where these are butchered for drag racing. When I bought this shell from California it was supposed to have a V8 implant and used for drag racing, but good thing is they did a very nice chassis reinforcing job.
lol, was just checking saw some in Japan but prices are shooting up lately as whole gulf is crazy about C110 and C10, infact one friend of mine just import KGC110 chassis no 93 out of the 197 ever made. Found one PGC10 the famous Hakosuka negotiation with the buyer in Japan though its a four door but decent car with decent pricing.
