For what it's worth, the local BBB rates them an "A". They've been registered since Jan 2010. According to the listing below they have had one complaint that was settled since then.
Per the review above, get anything and everything in writing, with any dealership or car lot. That's how the reputable ones (I use the term loosly) expect to do business.
Anytime you buy a used car (and I spent time in the business) always remember "Caveat Emptor",
Let the buyer beware.
Shields up, photon torpedoes armed.
