New to the forum, and possible new to MB ownership. I'm looking at a 2007 low mileage CPO ML350 for my wife. After reading some of the reliability issues, I have some concerns about whether or not a used ML hold up over the years.

My questions are:
- how good is the factory warranty? Hassle free coverage? Complete coverage?
- What non warranty wear and tear costs can I expent over a 4 or 5 year period (20,000 to 100,000 miles)? Am I really going to need tires every 1 1/2 to 2 years? Same with brakes? Anything else I should expect to break?
- Maintanence costs, currently have an Acura, oil change and std maintanence isn't much higher than a "normal" vehicle. How does a ML compare?

Thanks for your help
