Long time lurker here. Decided to make my first post.
I currently have a silver B7 RS4, 66k miles on the clock and in good condition. However, I really dislike the colour, its so "meh". Consequently I am considering a complete colour change by means of a full respray. I have already had a quote from Steve Ullman in Harrogate for £3500, which seems about right, going to get some more quotes though. The colour I want is Papaya:

So my question is, what are the cons of having a respray done? I intend to keep the car for the foreseeable future, so the resale value isn't a huge concern right now, but is something I still want to consider. I have a lot more mods planned such as KW coilovers, JCWeldFab exhaust, and eventually a supercharger.
I think because I went to one body Shop and they basically turned me away and said I'd ruin the car, I'm now concerned I will do just that.
