| In my view, a respray wouldn't work unless it was a proper job, respraying everywhere there's paint. In other words, like a restoration: take the engine/ plumbing out, door sills, carpets and everything else - very expensive.
Otherwise, if you do just the bits you can see, so that when you open the bonnet or look in the boot floor it's a different colour, i. it will look Mickey Mouse, and ii. when you sell the car people will think you had it sprayed after a prang, and no amount of explaning will dissuade them from that thinking.
The latter wouldn't happen if you had a proper job done, because it would be obvious that it was a custom job. Ultimately, this is probably more suited to i. Celebrities, ii. doing on an older car where you can spend a few grand and take it apart, which is not the ideal thing to do to a new car, especially as you'd lose your paint warranty. |
