The response time was good, Rene emailed me within reasonable time. Customer service is good. However, when it comes to disclosing issues with the vehicles Rene could be really deceiving. I was in the process of purchasing a 2007 Mercedes GL450, and had sent a deposit, but to my dismay the description of the vehicle on the website did not match the actual condition of the vehicle. I drove 10 hours. The ad said it the vehicle was equipped with “- Rear entertainment package with dual TVs” but one of the screens was not operational. It took 15 mins for the DVD player to operate. The floorboard was stained under the carpets, the liner on the ceiling of the vehicle was falling down, the rear part of the interior was torn up, several scratches. After I inspected the vehicle, I told Rene all of the issues I had encounter, she, however said that these were just “small issues” that I should just get fixed myself. If these were so “small” how come the dealer did not get them done??? She said, you can go on ebay or online and just buy a new screen for $150. My main problem was not so much that the vehicle has several cosmetic defects, but that the description of the vehicle made it sound like the vehicle was in great condition. “Condition: We are committed to selling only the finest pre-owned vehicles, and this Mercedes-Benz is no exception.” This vehicle was indeed not up to the standard the dealer claims to follow. Rene refused to return the money I put down to hold the vehicle, and also try to sneak a statement within the receipt of the refund for the down payment where I would “relinquish” my right to the return of such funds. Very sneaky. Needless to say, after reading this statement, I declined to sign it. I would just recommend anyone to find a different dealer, unless you want to be disappointed as I was.
