Abit of Buying Advice! Audi A6 C7

[JamesDReeve]

Hi guys!

I hope you're all well, as the title suggests I'm looking for abit of buying advice when it comes to the A6.

I adore the styling of the C7, and I'm coming from a E46 M3, need a better daily that will happily do 400 miles a week coming in & out of London. 

I've been looking at engine options and it seems the 3.0tdi is the best balance between power & MPG.

Is there anything I should look out for when asking sellers about their cars, and are High Mileage examples okay?

This is one I'm viewing tomorrow.
