These guys are out to rip you off and take advantage of you! CUSTOMER BEWARE of false promises during the pre-sale or post sale phases. I thought it was just my salesman, Michael Jenkins, but it was a collaborative effort from the service department to the management, Amadu in Finance, and Geoffrey McWharter the Sales Manager. I paid $15,000 cash for a 2007 230 Sport Mercedes from them and asked them to resolve three things: some scratches on the front bumper, get an extra key, and replace a 5 yr old battery that wouldn't crank the car. After the test drive the agreed to do this, so I paid a $5,000 deposit and went to my Credit Union to get the balance check for $10,000 and returned 2 days later to pay and pick-up my car, thinking that had done all they promised. A few months later after my car stalled and would not start, I found out that they purchased a new battery for my test drive, but returned it 2 days later to Advanced Auto for a full refund and put the 5 yr old battery back in my car. My wife and daughter drive the car and we found ourselves stranded one morning, and had to call for roadside assistance for a tow. Afterwards, I had to purchase a new battery. That’s when I realized what had happened, so I called and asked them to refund the money I paid for the battery, BUT THEY REFUSED...saying they were doing me a favor and we don't have $294 to give you for the battery replacement. Keep in mind they sell only luxury cars! This was totally preposterous and disrespectful to me after paying $15,000 for a vehicle! This is how they treat their customers!
