SL/R231: Extended Warranty....worth it?
I may be jinxing myself, but just looking through the threads on this, and the other forum, you see that the great majority of R231 complaints are constantly about lack of colors, body styling opinions, the merits of ABC or the 1960's era sound system. Whereas, the R230 forums list actual problems experienced by owners. Obviously, the R230 models are much older with much higher usage and mileage, so either the R231 engineering is turning out to be more reliable, or its inherent weaknesses are waiting to be revealed when a larger subset of cars reach higher mileage levels or are not properly maintained for a longer period of time.
My personal experience was that my previous 2008 SL550 did not have a warranty, but it was very reliable and that any minor issues were easily taken care of by myself. I then moved to a 2010 Aston Martin Vantage with very low miles, which thankfully I chose to purchase with a warranty. It had a very good service history, but it was frequently on the Aston Martin dealer flat bed going back for warranty rectification. I then decided that I preferred the incomparable grand touring manners and reliability of the SL, so I moved on to my current SL550. I did take the MB warranty for the current car, but only because of my poor reliability experience with the Aston.
To sum up. My feeling is that if you buy a lower mileage SL with a strong service history AND you are only going to do less than 5K miles a year in it, then it probably doesn't make financial sense to spend extra on the warranty. Put some funds aside into a car maintenance slush fund and enjoy the SL's incomparable GT cruising experience; assuming you can put up with the allegedly 1960's era sound system!

With that in mind, I plan to buy an extended warranty, when I purchase my car off the lease it's currently on. As with my first E550 Cabriolet, I'll shop a number of Mercedes dealers, throughout the states, because I've found that by doing so, I can save almost 30% of the cost of the EW.
As an addendum, when I started looking at the SL, I also looked at every other 2 seat sport/luxury car available, including the Aston Martin. I didn't want to pay full price for that car, so I was looking at 3 to 4 year old versions. Talking with the salesperson, I found that AM owners usually put on less than 4,000 miles a year on their cars. I asked what an extended warranty would cost, and was told "a little over $8,000 a year. That was when I determined that owning an Aston Martin was not for me. Conversely, I expect that a MB extended warranty will cost perhaps $3,000 for a three or four year product. Money well spent, I believe, based on my driving habits.
