I've recently been wanting either an R or Tri-z, well theres a guy that wants to sell a triz that needs a motor. hes asking $400 dollars, however he will take $300 for it from me. he also has a header, two silencers, the carb, and rear shock. there is a guy that is selling a whole tri-z motor in his area for 250 bucks soo for $550 i would have a tri-z. is it worth the risk of things being cobbed together on the engine or on the Z? it's in decent condition okay tires, and red and black plastics. would you buy this?
