For Twin-turbo V8 has 517bhp, which is plenty. Acceleration is unsettlingly quick; the handling is reassuringly secure. Brilliant.

Against Officially, it'll do 28.5mpg; realistically, you'll get nowhere near that. It's also a four-seater only. The steering could do with a bit more feedback, too.

Staggeringly quick and capable sports saloon - but with pretty monumental running costs.

Buyer's notes

Target Price team says:

Every Mercedes CLS blends sleek, coupe-like styling with four-door practicality, but it’s important to spec your car carefully because there are three suspension setups: air suspension; steel springs with adaptive dampers; and a Sport option that uses firmer steel springs and dampers.

We’ve sampled the air and adaptive systems, and there’s no denying the comfort gains the air suspension brings. The steel spring cars are noticeably firmer, but the upside is they’re more agile.

When it cxomes to choosing an engine for your CLS, it’s hard to look past the 2.1-litre diesel (which is rather misleadingly badged 250 CDI). It doesn't sound quite as creamy as the bigger engines, but it gives strong performance and affordable running costs.
