Wasted my time, not courteous at all of my time. I came to view a car and told the salesman I was on my way that morning and then after I show up and wait 30 minutes he tells me they sold it yesterday. Then he starts bringing random cars for me to see. I asked for them to appraise my car and they never even did that. I ended up just walking away, one of my worst experiences at a car dealership
