I have a 2008 SLK 350 with 29000 miles. Took it into the dealership yesterday and discussed costs/mileage/years for extended warranty. $3049 seems reasonable to me for a warranty that will expire in January 2015 and goes to 75,000 miles but I wanted opinions before I jump in. To increase it to 100,000 (same year) the cost would go up to $4100. I've been reading past threads on this topic this morning and I see now that I forgot to ask about the deductible and apparently I can ask for a copy of the warranty to look over before purchase, which I also did not do. She told me it covers everything but wear and tear items such as hoses and belts, and cosmetic issues. I do intend to keep this car through 2015 and beyond, and I do have another vehicle as my "daily driver" so 75,000 miles shouldn't be hard to stay within. It's my first extended warranty purchase ever and I don't want to look back and wish I had researched it more! To me, my big concerns should be the a/c and heating system (I live in South Texas, a/c is a HUGE concern actually) and electrical, as these are the only things I've ever had trouble with in other vehicles. Does anyone have any suggestions/opinions on this?
