I would keep the Si. Judging by your mods so far, you're obviously well on your way. And most mods make your car less valuable to Joe Consumer, so you'd be pretty unlikely to get back what you put into it. Plus, the used car market is a bitch. Its such a pain in the ass to sell a car for what its worth to you and to find a car thats just right . Make it easier on yourself... just keep the car you got.:thumbup: *
