So Im looking for a DD so I have work on my Trans Am for bit. Ive always been fond of the 3rd generation civic si's. The body style just appeals to me more than other gens. What are things to work for when purchasing one? Because I couldnt find anything relevant to civics, just the crxs. I also plan on modding, or even swapping the motor in the car. Any help would be greatly appreciated.
