I dropped my car off at Ultimate Sunday evening. They were closed so I dropped my key in the drop box. Monday morning when I called at 9:30am, Raul (the owner) picked up and had already fixed the car. Bad ignition coil.

Total cost (parts/labor/tax) =$240.

Starts right up and has no rough idle either.

By the way, I highly recommend this place to anyone that is in the South Florida area. Seems like a great shop. Raul is really nice. Prices seem fair. There must have been 20 older model Mercedes at his garage when I picked my car up this afternoon.
