AutoNation Buick GMC Park Meadows

They are all about touting their "no questions asked, 500 mile/5 day" return policy, but just try doing it and they treat you like crap. What took 30 mins when I bought the car (swapping tires between cars) took over two hours to swap back, when I took the car back. Little things like the cigarette lighter didn't work, which may not seem like a big deal, unless of course you want to charge your phone while driving...and the salesman says "it's not on the multipoint checklist they do on cars and it's not that big of a deal" is a deal breaker, as it's the little things that cascade into bigger unseen defects. What else did they overlook and/or hide/not fix, because "it's not that big of a deal"?
