Aftermarket fenders will cost a minimum of 150, plus shipping, WITH a body shop hookup. Add about 200 plus for install. Then add about 300 for paint. Ask her if she think it's worth 700 bucks. Yeah, that's for ONE. Dealer cost, over a grand all told.
The fender is a bolt on, but it's non-trivial, and takes a good while.
