I cant help with a recommendation for someone around Berkshire, But i'm awaiting delivery of my MS so have been calling around Manchester area for quotes after 5 quotes the prices are all around £1700 for full colour Vinyl Warp and £3500-£4000 for full PPF. I asked the difference between the two and was told the below :-
" The advantages of this film over the vinyl wrap is that it is a self healing film and much thicker! This prevents stone chips and scratches on your paint! The film comes with a 5 year warranty!"
