Mercedes-Benz has introduced a scrappage scheme, offering up to £7000 off a new model when you trade-in your old diesel.

Diesel vehicles must be Euro 1 - 4 to be eligible for trade-in and customers must have owned the vehicle for at least six months. The scheme cannot be used alongside any existing finance offers.

If your diesel car was built before 2010, it's likely eligible for the trade-in bonus. The scheme ends on 31 December 2017, however, Mercedes-Benz estimates the delivery dates as from now until 31 March 2018.

Smaller models like the A-Class are available with £3000 savings, while the C-Class saloon and estate come with a hefty £7000 discount.
