Here is my advice: research an extended warranty and buy one. I purchased an extended warranty through Chrysler. Shop different Chrysler dealers- the price varies (hard to believe) The used CF I purchased had 42000 when I purchased it almost 2 years ago. I have made 3 claims, cost: $100 per claim. The repairs would have cost easily over $2300. Mercedes engines are complex and expensive to work on like any highly precision engine. There are MANY very qualified CF owners on the forum who can give lots of advice and direction concerning repairs, resources, etc. If your "handy" and a mechanic, that is one scenario. I am not an auto mechanic and don't have the time to try to do repairs and possibly cause more damage. You have to decide your comfort level. The prices of CF continue to drop so you can get a good bang for your $. I flew one way to another city and purchased mine. Add in the extended warranty if your budget allows, you won't be sorry.
