There has also been a wide range of engine options, with petrol, diesel and hybrid on offer depending on the age of model you choose.

Mercedes C-Class Mk3 (2007 - 2014)

The third-generation C-Class was a welcome, and much needed, return to form for Mercedes in the small executive saloon and estate sector.

Mercedes C-Class Mk2 (2000 - 2007)

In a rare moment of trying to follow the crowd, Mercedes built the second-generation C-Class to have some of the attributes of its arch rival, the BMW 3 Series. This meant a sportier look for the small saloon and estate models, plus a driving set-up intended to deliver more involvement.

A budget of £1000 will find you a first-generation C-Class, but it’s going to be a tired example with rusty wheelarches.

What's the best Mercedes C-Class Mk1 to buy?

A diesel-powered first-gen C-Class will get you there with good economy, but it will be noisy and slow progress.
