That second R32 Vspec you linked is mine. I do have import paperwork with the ks that are on it. Its a very honest and tidy car. Im a bit surprised it hasnt sold, I wouldnt if I didnt have my eye on something else.
Paint on the plenum can be a guide, but the reality is that if its been pressure washed at all in the engine bay the paint is the first to go. Wouldnt be that hard to touch up, if your that way inclined. Look for signs of overspray, if its all fesh looking and black, cause its very unlikely to have been removed to be painted, unless the engine is out.
