Just out of interest has anyone compared these two?
Never had to use AdBlue on any diesel I have had (or if I have - I have never added any!) - is it needed on the XE? And how often do you top it up - my last two oil burners were my XF and and E-Class, neither of which have received any AdBlue goodness from me!!!tristan said:With the auto, CO2 is 106g for the 163 and 109g for the 180 (111g on 18" wheels), so it's a no brainer for around £500 ... performance, larger fuel tank, larger ad blue reservoir, twin pipes etc. Manual gearbox is 99g and and 109g respectively, so a tougher choice re. tax.
I opted for the Prestige 180 auto (with electric seats - yes, I paid for them!) over an R Sport 163. I guess some don't have a choice and others will compromise performance for styling.
