To paint my T4 original white-no rust and a few dings mainly in doors £1500+ and i would say you could go up to £2k easy!
Wrapping could be cheaper if your body works tip top and is basically a clean and wrap-don't qoute me on this mind as although i have in the past sprayed the odd car vinyl wrapping is way beyond me I:
Have a look on web or no doubt someone will gen you up on hear- good luck with your choice T:
I think the wrapping is a brilliant concept and allows so much more design than a respray ever could with all sorts of graphics available. Good points for me would be a cheaper price, more available/versatile designs, easily removeable, and also protects your paintwork.
If the cost is not significantly cheaper than a respray though there is a disadvantage, as i think wrapping is only designed to last approx 5 years!
