You need to paint it. The primer look doesn't work on a 2002, it's a car that doesn't belong in the junkyard and i think the primered look does that to a car.

Save the money to paint.

About the dual front headlights. - It doesn't work, i've seen it done and it the lights are to big for it to look right. That's why they are smaller on the E21 Bmw cars.
