Sales staff condescending and rude on phone...still posting cars on Web site not for sale. I have been in business for many years and don't understand how management accepts salesman Sean to speak to potential customers so rudely. After visiting and speaking with sales mgr was told that the car I was interested in purchasing for my son was a mistake and should not have been put on Web site...still on site......hopefully owners will take note and resolve some integrity issues..which give car dealerships a bad name. Have delt with lan mercedes for many years back when they were at old location..good old days..I would rather have smaller and friendly then glitch and glamour show rooms...very disappointed. Bob
