I must've been mad then
A few years ago when I desperately wanted some Ceramics, I purchased a Black Avant with Ceramics for £19,750 & a flight to Scotland, the Ceramics were then swapped over onto the Blue one I had. The donor Black RS4 was sold some 18 months later for £21.5k with about 8k more miles on the clock. I did sort it out into a sellable condition though, by refurbishing the Wheels & Mirrors in Titan colour, new mirror base plates, 4x new Michelin tyres and new TPMS sensors, Auxiliary Radiators, 2x new headlights, parking sensor, CV boot, Audi Service & MOT. Along with a good machine polish and detail by myself.
So the Ceramics probably cost me no more than £1500, but they easily added £2k to the price of the Blue car - which I eventually sold and miss loads, thankfully it's still on the forum with a fellow enthusiast.
