i have never owned or know anything about rx7's.i have however come across a CLEAN 87gsl with 18 inch rims.he says 2500 but i got him down to 2000.the car is veryvery clean for the prize.the exterior is all but almost perfect.and the engine turned on instantly,it has webers,exhaust the whole shebang.but i know nothing about rotarys being a honda driver all my life.what would be signs of something wrong with the 13b??what should i look for in this car as far as defects??what type of support is there for these cars??how easy would it be to get someone to switch out and install a decently new engine and how much would it cost??etc...i just need guidance.being a puerto rican born and raised i know what these cars can do.hell 510's with 13b's are the norm back home but still i need help.ohh and is 2000 a good price for one of these in the u.s.a.??they would sell a 87 for over 3500 back home.
