You can choose museum delivery for your new Vette, why not make factory pickup an option for new vehicle buyers? Seems like the cost of delivery factored in the price of vehicles would more than pay for an on site pickup program and some kind of associated factory tour, regardless of which vehicle you buy. I bet a fair number of people would make a new car purchase pickup a mini vacation of sorts.
Edit: If I was plunking out a premium for a c-8, I'd have no problem picking up my new ride from Bowling Green.
