Used test: Audi A8 vs Mercedes S-Class

Buy either of these two superb luxury cars at a couple of years old and you'll save yourself a fortune. But which one should be top of your list? We have the answer...

Used Audi A8 Saloon (17-present)

Our Verdict

The S-Class wasn’t going down without a fight, and it’s still as good a luxury car as it has ever been. It has a strong yet smooth diesel engine, is more agile than the A8, has a better infotainment system and is slightly cheaper to buy at this age. The S-Class still very much deserves its five-star rating.

So it was always going to take an extraordinary luxury car to beat the S-Class, but the A8 is just that. It manages to feel even sturdier inside, is quieter on the move, has an even plusher ride and comes with more standard equipment. It’s also a solid used buy, with stronger residual values than the S-Class. Victory for the A8, then.
