My advice is if you want to be successful with this one, you'll have to do a core exchange program of some type.
Problem is a lot of people only run 1 car and can't go without wheels while you're doing the work.
You want to appeal to the masses, get the biggest customer demographic you can, at least that's my opinion....and I've had a lot of business development expirience.
It's all about making it easy to do business with you.
Anyway, I'm onboard with this one as soon as I can buy a second set of wheels....until then, I'm just one of the wishful people on the sideline.
Good luck! I'd like to see this one succeed!
