If you value your resale DO NOT let a dealer organise to fix the paint.
If you have rusting hinges, unbolt them and either strip them back and paint them up yourself in a contrasting colour with a textured finish (like the flares) or go for stainless/anodized hinges from the states. Or buy those chrome hinge covers and prep them up and paint them bodycolour or something.
