Can you check to see if they can offer a pre painted version?
Perhaps they can make it a bit less costly with a simpler finish before painting to get painted total cost to a reasonable level.
Or, make units that are to be painted or wrapped.
I prefer my cars, most of them very highly modded, to look pretty stock as less attention is good, if I want to prove something I prefer to do it on the track
I would even take a blem one if that happens, for the right price.
