You are about to be scammed. First, buy locally to you, or at least the nearest state to where you live, if outside your own.
You will SEE the product itself in person, KNOW it's being prepped for you, SEE the figures being worked on because you'll be seated in the dealership etc.
Would you buy a home without sitting down with a realtor, or the owner of the home? No
You may wind up paying money and getting no vehicle
