Well here I am in the Gen2 world. I was looking to buy a Bentley Manual for my wife 2014 R57 but it only goes to 2013. Then I released the Gen2 cars stop at 13 except the R57. What year did they switch to the N18 engine? Also what should I look out for? The car has 52k on it but I would swear it is new. It was well taken care of.
