Debate which car is the better performance "value" all you want but let's not start silly debates on which engine is better.
S65 isn't bad, I believe the N54 has won more awards, and recognition for engineering. S65 didn't really distinguish itself among 8cyls, like the N54 did in the 6cyl category. But what do a bunch of professional engineers know anyways?
