Thanks your advices! The N63/S63 engine has 3 upgrades. The latest one is 2016. After that S63 engine is pretty similar to F90 M5's engine. I agree with you that M5 is a car with performance and luxury. And the price is lower than E63 AMG. For the extend warranty, do you have any good suggestions? I heard there are two kind extend warranty. One is only protect your power train another is protect your whole car.
