Alfa to Audi

[bluepowell]

Hi everyone.

My well loved 07 plate Alfa 159 estate is getting long in the tooth (and a bit creaky) and I’m considering a Audi A4 or A6 estate to replace it.  Considering the cash I have a 2015 A6 model seems about what I can afford. Newer if A4.  

Has anyone any tips/ things to look out for on the A6?  

Also, what kind of MPG can I expect?  Averaging 42mpg on alfa, with short trips 20/30 min trips to work in the week and at least one run out per weekend.  

Thanks for your help in advance.
