Saw a white lexus is350 they advertised for a good price; called them to Inquire and apparently the vehicle wasn't listed at the price I mentioned and basically told me I was wrong; I do have a screenshot of the price, tried going back and the price had dissappeared and adjusted for 8000 more; baiting customers with a low price is unethical, and telling me I had the wrong price is just simply poor customer service especially when I had 3 other friends check the same vehicle;
