M5 reliability and maintanence costs
Hi all,
I have someone who may be contemplating an F10 M5 purchase. What is the reliability like on the 2013's? What are the issues that typical cause a headache and what are some running maintenance costs that are typical?
Car would be coming with remainder of factory warranty.
Thanks Ahead
