Used Mercedes-Benz E-Class Estate 1999 - 2003 review

The E320 CDi turbodiesel is easily the pick of the bunch, thanks to its brawny 3.2-litre engine. At its best when coupled to a five-speed automatic, it will return 36.0mpg.

The E220 CDi diesel is also a sound choice if you don't mind trading some performance for greater economy. It'll return up to 46.0mpg.
