E Class Estate - 13 - Thoughts?

[Sir Bagalot]

Looking at changing. Like the new shape E Class and thinking 13/63 reg, AMG spec.

Some Q's

What is the real world difference between the E220 and E250?

MPG is important, my days of driving fast are past, and when on a Mway tend to set cruise at 60-70, my right foot isn't heavy, so what is the realistic MPG?

Also any options must haves?

Also looking at BMW 5 series, and possibly Jag XF SB
