2016 a6

Hello! I’m currently looking at 2 different 2016 A6 premium plus cars. One of them is the 2.0 turbo and the other is the 3.0 supercharger.

The 2.0 has 81k miles, the 3.0 has 87k.

Both are close to same price (~$500 difference plus taxes/fees) and both are immaculate inside and out…. Which would you choose?

I’m new(er) to the brand so I’m unsure about engine reliability and/or cost to maintain (outside of regular maintenance). Any advice would help!

Tl:dr 2.0 or 3.0 engine?
