I purchased my GTS from Bruce Venable. He is the President and the owner of Vipermania. He lives here in Cincinnati Ohio and is the design engineer for all the products as well. He also is a broker. He is a very honest man and would trust him as much as you could trust another person.
If he has a car here locally....I would be happy to look it over and take pics for you.
Here is his # if you have not talked to him yet...
