I previously wrote a review for this dealership while in the process of purchase our used 2010 MB GL450. My husband and I declined an extended warranty based on the fact that we had been provided a checklist sheet from The Auto Source from MB Coral Springs summarizing that car had no faults. Less then 4 days later, the ABS, ESP light came on and a fog light warning came on. After the brakes locked up on their own several times while driving the car (with my infant in the back seat), I called Auto Source to let them know. They informed me that there was nothing that can be done bc a warranty wasn't purchased. Two days later, I brought the car to Mercedes to be informed that all four wheel sensor lights needed to be replaced as well as a harness. The bill was just under $1k. Again, I called Auto Source to let them know and they informed me there is nothing that could be done because a warranty had not been purchased. I understand that a warranty was not purchased; however, I assume that all 4 wheel sensors and harness did not all of a sudden go bad after driving the car less then fifty miles. Perhaps it is just a coincidence, but it does makes me wonder.
