You have to admit that it'd be a pretty sweet deal to be able to order a car and pick up a model of the same one you ordered and experiment with paint jobs. I think that would be an insane marketing tool as well as bringing a steady stream of cashflow into the business as a lesser priced item would sell more quantity and be able to be ordered online or for walk in customers. I mean if you could get a model for say $60 of the car you are dreaming of and work out the paint job and everything and then walk into Fran's shop yet again when you have funds in order and plop that thing on the desk and say, "Build me this", I think it'd be great.
But alas, it is time spent out of pocket from designing the REAL cars, and as we all know that's where the money is. I think it'd be a sweet idea and one you may consider, but I dunno. It's definitely something that would sell, that's for sure.
My $0.02 on the whole deal,
Brian
