it wouldn't be worth anything. It's a civic with a newer civic front end... nothing special. Plus, with the 96-98 civic SiR front bumper and lip on your car, You'd have a very nice and very clean Civic. Don't fall into the norm of having something everyone else does. Leave the front end you got and spend the money on wheels or paint or something worth it. Doing the front swap, it will just look like a 99 civic. nothing more nothing less.
