BOTTOM LINE: They don't know the quality of their vehicles (or will hide it from you if they know they're bad). Once you write them a check, they don't care about you anymore. They're non-negotiable, and they tack on a lot more cost than they should.
MY ADVICE TO BUYERS: You might as well buy a car from a private seller on Craigslist, eBay, KSL, or the like. At least that way, you know the previous owner, they'll probably be more honest with you, you won't have to tack on any extra fees, and the quality of service once you drive away will be the same it would be here at Beehive anyway
