Well it wouldnt be a bad idea to get the Civic but there isnt any mods you can really do to it whatsoever unless you want to spend alot of money. It's carburated, they dont make body kits, altezzas, etc for it if that's what you like. You could get it and put on some nice rims and that's about it. By then you still should have enough money to get a CRX for pretty cheap. If you dont want to swap the motor in the CRX then stick with the Si.
