Just bought 2007 SL65. Factory warranty expires in a few weeks and am pondering an extended warranty from MB. Price is steep ($4.5k for 3 years and 75k miles). My logical side tells me the odds are against ever needing to spend $4.5k in repairs in the next 3 years, but I have seen all the posts advising to "get the warranty." I understand the "peace of mind" aspect of a warranty, but I would rather base my decision on what some others have actually experienced in terms of repairs needed and costs if known. So, would love to hear from other SL owners (especially AMG) as to how often they have had to get repairs, what kind, and at what cost. Thanks in advance.
