It is significantly more comfortable and grown up to drive. The standard equipment is very generous too with lots of bits I didn't have before like the HK speakers, Head up display and Comfort Access.
Try them both and see what you think but unless you're desperate for the slightly better performance/ soundtrack the 8-series is better IMO.
Oh and on the fuel economy I'm seeing about 35mpg long term from the 840d whereas the Z4 sat at 28mpg so a slight improvement there  |
Wow. I get 12mpg on the 'drive it like you stole it' cycle—but 12 (s)miles per gallon is a reasonable return I think.
