2017 is a great year for the 5 Series! from what I've read! It really depends on you, on what to get, you should ask yourself what is the main reason you will be using it for? (Commuting to work and back, 2nd car or your weekend driver?) Do you plan on using it for the purpose of saving gas saving money? Or do you plan on using it as your performance car or plan to Mod it? 40k is an absolute great budget for a used 5 series of the latter to be honest. If I were you, if I was in your shoes, I would go with that robust 540i with the B58. Still great on gas however you are in Europe so really you got a big decision to make here.

Certified used is very nice and a Extended warranty is nice to have however, how long do you plan on using it or plan to keep it after its warranty?

2017 I recommend the year to choose a 5er!
