Leeds Motors, who are sponsors on here, painted and fitted both mine and my brother's aero kits on our MINI's, and I can vouch that their work is absolutely spot on. In the link you'll see that they estimate a full respray costing between £1300 and £1500, so its not as expensive as you might think to have done. And as for the aero kit scraping every speed hump, and the front splitter hitting everything, that doesn't happen. I've only ever grounded it on a particular very steep drive way so it's not too bad. Does look awesome as well!!
