"Was it expensive to have that done?"
I ask, do you mean, did I pay someone to do that, he nods yes, and me, being in a kinder than usual mood, reply that I did it all myself, and that I'm not sure if you even could hire an auto-detailing place to do that kind of work.
But I think this would be a funny thing to do: Go to an autodetailing place/paint shop with pics of famous artcars (Carthedral, Camera Van, etc), and ask, how much to get my car to look like this? especially if you have something like a Toyota Camry and not a hearse or a van.
