xfr vs rs5

[Mirinjawbro]

Hello

have made a couple threads recently and have narrowed it down to 2 cars.

a 2011 RS5 or a 2011 XFR. (or 15-20k examples)

i prefer the looks of the RS5 but everything else sways towards the xfr - comfort - mpg - speed etc

anyone with some expertise on whats best?

problems? overall running costs? ease to upgrade? (i always tinker with any car)

thanks
