What alternatives should I consider to a used Mercedes-Benz S-Class saloon?
The latest (post-2017) Audi A8 is if anything even quieter than the S-Class and rides just as well, which is really saying something. Previous generations were pretty good, too, although there was a slight gruffness to their diesel engines and their ride left a little to be desired. They make a fine used buy, though, with good-value models widely available.
The latest BMW 7 Series is a technical tour de force, with almost as much luxury and safety kit as the S-Class. Used examples now make for secure buys, and the driving, interior and standard kit all match the expectations of buyers in this market. Earlier generations aren’t quite as impressive, but find one that's reasonably priced and you’ll still enjoy luxury motoring on a budget.
