Did ya know that if you order a new Corvette Z06...For an extra $5,000.00...You can go to factory and participate in the building of the engine.
This is not a new idea though. But, it's about time GM caught on to it.
For years, I've charged people extra if they want to lend a hand while I work on their vehicles.
As i'm sure Mark would charge a person double if they wanted to help him wire their place of business.(heck, double may be a bargain!!)
