went to see a local guy the other day for the vinyls to be done, got a quote for the vinyls seen on the photoshop with a few custom bits, roof in black vinyl and the door frames where the winddeflectors go in black vinyl too for £350 which for supplied and fitted i thought was a very good price.
hopefully will have these on in the next few months
When you take your car in to have the graphics applied, make sure there is no wax or your car otherwise they will be peeling off as you are driving down the road a few weeks later.
They should do it for you, but I have known of some graphics companies that haven't done this and people have lost alot of money.
To be honest I'd say decals are best bold and simple, as from a distance that'll just look like you've driven through mud and got it all over the paintwork. Mind you, i suppose it'll mostly be seen in traffic or parked, nonetheless I'd far sooner spend £350 under the bonnet or somewhere else entirely...
This car was done over 12month ago and has not long since been put back to standard and sold. The graphics were applied though and were on for quite a while.
