so, I have a 2013 Audi A8L now, love it but it's getting long in the tooth. I had a 2011 750i that I enjoyed but needed change. It's time again for a "new" car - thinking of a 2016 750 xdrive with 34k miles on it but not sure how they are for maintenance, issues, etc. being the first year. Other option is a 2018 540 xdrive for the same money, less miles... but it's not a 750 obviously...
