Which used Mercedes S-Class saloon should I buy?
Choose the S350d and you’ll be getting one of the sweetest and quietest diesel engines around. You really would be hard pushed to tell that there was a diesel engine beneath its bonnet.
We’d seek out the AMG Line trim, because this keeps costs down (in relative terms) and gives you all the goodies a car like the S-Class deserves and expects. We’d also look for the long-wheelbase version.
