Which used Mercedes E-Class saloon should I buy?
The diesels were the most popular models when the car was new and they remain so with used buyers, thanks to their ability to cover huge distances with reasonable economy and good refinement. Our choice is the E320 CDi, with its 3.2-litre six-cylinder turbodiesel that's capable of 36.0mpg.
The smaller E220 CDi turbodiesel is the best bet for anyone who wants good economy because it can manage up to 46.0mpg with a manual gearbox.
We'd avoid the smallest petrol engine, the 2.0-litre, as it just isn't strong enough. Much better are the 2.6, 2.8 and 3.2-litre V6 petrols, with the 3.2 the pick of the bunch and handily the most common of this trio. The petrol V8s are slick and silky in their delivery, but too thirsty to be recommended.
Classic trim comes with all of the luxury and safety kit you'd expect, so it should satisfy most buyers. But, if you want more, Elegance throws in alloy wheels and Avantgarde adds sportier suspension.
