When I get my Ed30 I shall be looking into the possibility of repainting it in laser Blue. I reckon it would re-sell ok, as it's such a popular colour on the mk5 scene. In fact, if done properly, It might even add a premium. However, my number one priority is getting the car I want, as I fully intend keeping this one long-term, so the 'resellability' is secondary.
Your thread has, however highlighted the importance of having the engine removed. I'd be put off buying a car with a different colour in the engine bay.
I don't think anyone would buy an Edition 30 in a non factory colour.
I would , if it was a colour I liked and the job had been done properly (engine out , windows out etc). I dont care about resale value , I care about enjoying what I have at the time , and if I liked the colour I would have it. For instance , i wouldnt mind an Orange one , or Bright Yellow , I like bright colours!
