I wrapped my Lambo pre-delivery i.e. no use at all. The reason was two-fold:
i) to avoid stone chips on the paintwork - its low, its going to get chipped
ii) I actually wanted a matt style finish. To buy this cost £10k and it came with the warning that if you ever needed to do anything to the bodywork, you'd have to respray the whole car to get the colour blend. So, I took "standard / free" paint and spent £5k on a high end wrap, which was a clear matt on standard grey metallic paint. I was forewarned also by the dealer that you've really got to have the front wrapped anyway regardless of colour - or budget for a respray at some point. I frankly couldn't have been more pleased with the result (much better than matt paint):
As a result I've changed my views on wrapping. Plus, its your car, do what you want to it. That said, I chap I was talking to at a show recently had been to look at an Aventador (owned by someone from One Direction - I had to ask as I vaguely recognised the name). It had been wrapped, so they asked to peel a bit back and it wasn't pretty - apparently a bit of paint came away with it. I guess that's a case of being aware of who's wrapping your car and what they're using to wrap it in. Mine came with a 5 yr guarantee on it from Topaz, who are highly regarded.
