400E/E420's power shines at speed higher than 40kmph, particularly when kicking down for speed at 60kmph(37mph) and 120kmph(75mph), these are 2 killer power bands of 400E/E420, gear will drop to 1st and 2nd respectively, 1st gear will pull to 80kmph and 2nd gear to 140kmph!
It normally blows competitors away in these 2 bands. Overall they are built as highway cruisers, my drives are 95% highway, so I like it dearly.
For stop and go traffic at any speed lower than 40kmph, don't even try to race with a Corolla, IMO, tall gear along with excessive understeer are the biggest shortcomings.

Still missing the days with the Benz, it kept me busy.
