Are you willing to share what artwork like this would cost to created?
Sure... a two car design like this, with type, simple background graphics (including seps in PS channels) go for $600-700 and I retain rights to re-use the vehicle illustrations down the road. Add $50 for additional locations... chest or sleeve prints.
Add a third car and/or some kind of background scene and price goes up from there. Also, cars with more detail or complicated paint jobs can bump the price up a bit, but that's where most of the two-car show designs sit nowadays.
