If you strip and prep the car your self you could half the price. Doesn't look that hard if you watch 'Wheeler Dealers' on the satelite channels. Change of color may be harder due to needing door sill painting etc. 3000 euro would be at the higher end of the quotes i would think. Unless the car is special probably not worth doing at all. Price around and get references if possible. Don't forget to show us before and after pics
