Buyer beware: Check the vehicle's mileage against what is stated on the sticker. I know used cars will be driven for test drives and maintenances, but that should never amount to hundreds of miles added to the odometer (like what I saw on one vehicle). What's worse is when the dealer openly admits family members are driving the cars for sale around for their own private use, even "picking the kids up" in them, so that they aren't even on the lot when you come to take a look. (Meanwhile her significantly older version of the same car was on the lot. Gee, I can see why she prefers the one for sale!) In the case of that vehicle, it was advertised as a One-Owner car on Carfax, but the dealer has essentially violated that fact. To make up for it, he showed us another one not yet up for sale. Oh by the way, they drove -that- one to a vacation and back! Is there a car on the lot that they -haven't- had a fun time racking up mileage and wear and tear on? I felt like this was a huge breach in trust; what else are they doing (or failing to do) with these cars that they aren't telling the buyer about?

Overall it felt like a very unprofessional, lackadaisical atmosphere. Whatever the price or statistics on the car, I did not feel comfortable shopping there.
