The first thing to look for is an even shade of colour across all panels. Sciroccos are harder to match paint on than most cars, which is partly down to the colours offered by Volkswagen and the curvy nature of the body.
Some owners have reported problems with the frameless door windows in colder weather. The window glass can freeze to the frame's rubber seal and stop the window from dropping as the door is opened. This can tear the rubber seal, but it's easily avoided by spraying the rubber with a silicone lubricant on a regular basis.
Early models had a problem with the tailgate struts rusting, but they should have been swapped under warranty by now. Otherwise, just the usual checks for damage apply to the Scirocco's exterior and alloy wheels
