Our 2007 Cl 550 with only 19,000 miles on odometer experienced an instantaneous and devastating oil leak that covered the entire. engine compartment with oil. I had thought it was a power steering related issue as when the oil leak expressed itself, at the same time the oil leak became apparent, the PS system failed. Upon recommendation from a friend, I had AAA transport the car to Elite Mercedes for analyses of the problem. Within 5 minutes Raymond Lam, one of 2 owner partners of Elite, determined that the engine had blown a oil filter gasket which had initiated the spraying of oil about the engine,,,along with additional assistance of the serpentine belt system. Given prior experience with dealership service departments, it is entirely possible that such a rapid analysis and subsequent repairs and cleanup of the ungodly mess under the hood would have taken substantially more time,,,,and at a significantly higher expense. Car was done and ready for pickup the very next day....I did also request a full service of the car including a coolant and brake fluid change. The costs were very reasonable and the cleanup was excellent. My first experience with Elite and certainly will not be my last. I do have a great deal experience with working on and showing my small collection of old classic American muscle cars,,,,so I do have substantial experience in this area. I recognize and appreciate talent and honesty when it comes to these old cars. Ray displays both. Roger Schaaf
