plus mugens dont break, if every shop has the parts for your car then why? does that car break alot, probably.
the ntc3 has been out for so log shouldnt it be the most popular and most stocked in terms of parts?
look at mugen serpent and trinity they are always looking for another improvement to make thier car the best, i think the tc3 has been out about 4 years or more, correct me if i am wrong.
