When I got the kit, there were quite a few scratches on them, some deep
and it took me the better part of 4 hours of sanding, primer & paint.
Then another 5 hours to take out the old headlights and put in these new lights.
I had to drill four holes in the recessed lights base to bolt to where the pop-up lights were.
Anyway you look at it, you will have modification, touchups, maybe repaint to do.
The headlights covers are a very tight fit and you WILL scratch the paint putting them on.
Not an easy job... but I do like the way they look. Unlike the other C3's.
