Which used Mercedes E-Class saloon should I buy?
Of the eight engines available, the diesels are by far the best options.
The 168bhp E220 CDI is a great starting point to the range, and the most common on the used market. Although it's not fast, it has enough power for a car of this size. The 187bhp E280 CDI is more enjoyable to drive, and a good trade-off between power and economy. There's also an E320 CDI with 221bhp, but it's not that common.
