Just joined 13 C7 S6 sayin hello

[JLam13C7]

Hello all,
I just joined because I just purchased my first Audi. I’ve been driving BMW’s for the past 20 years.(2002, 540 wagon, 535, 335 convertible).

A friend of mine was going to trade-in his 13’ S6 with 64,000 miles. For a Ineos Grenedier. what the hell… sell to me? so he did.

original owner, He had every receipt. turbos went at 48k they were replaced and upgraded. But he doesn’t know the details on the turbos. (I do have his mechanics contact info so I can find out.) lower control arms were replaced as well.

And …..I think I’m in love…

I have never in my life driven a 4,000+ lb four-door that was glued to the road so well, pretty damn balanced, And like bmw, I feel very connected to the car and the road. And…

and…..THIS CAR HAULS Ass!
Sorry for being long-winded can’t help myself

?? Is there any preventive maintenance I should be doing or should have been done already?

Thanks in advance for reading and commenting
