 This is my 2nd M5 - I had owned the e34 chassis and I can see as well as feel certain shared characteristics.  The e39 works perfect as I have a family that can all fit, and the trunk is larger than most.  This car has exceeded my expectations in every way...quality, performance, did I say performance. Car is well suited for my 21 mile rt work commuteor 500 rt trips up north to the white mts where you see this car shine.  The engine is very powerful, yet flexible and practical..3 or 4th gear pulls from 30 mph is no problem with that massive torque behind you.  I am very lucky to have this car. And 23mpg (hwy) is not too shabby for 400bhp 4000lb vehicle.
