Audi has built-out massive service garages. That should say something about their profit model. To be fair, many other car mfgs have done the same. ... even Lexus.

Also, fwiw, while Audi has some great styling, they lack, compared to MBz, for serviceability. --Audi really pack the cars tightly with fragile electronic devices in hard to reach places.

I say that from my experience with a friends A4, and another S4. The A8 may have more room under the hood. tho, still, I would be a bit fearful of the more rare parts of the A8.

I would highly recommend a similar year S-Class Mercedes. Those are some tough cars. Top-notch build. Very serviceable.
