Buying a used 2010 Mercedes S-class petrol

What is your advice on buying a used 2010 Mercedes S-class petrol?

AAA A used S-class in good condition is worth considering and will give you a special sense of luxury. However, being a 2010 model (which is a generation older than the current model) it is well out of any warranty period and is at an edge where parts will need frequent replacement; this could mean expensive maintenance bills.
