What used Mercedes C-Class saloon will I get for my budget?
The C-Class has enjoyed considerable success in the UK over the years, so there are plenty of examples to choose from. Indeed high mileage ones can be bought for around £9000, but we'd recommend spending upwards of £12,000 to secure a car from 2015 with average mileage for the year, and full service history.
Spend around £16,000 and you could find yourself with an immaculate 2017 C220d Sport, our chosen trim, with an average mileage from an independent dealer. Meanwhile, you'll need around £20,000 for a facelifted late-2018 car. Spend between £20,000 and £25,000 on a good 2019 or 2020 car.
If you're feeling tempted by either of the AMG models, budget on £28,000 for a C43, or £29,000 for the full-fat C63.

How much does it cost to run a Mercedes C-Class saloon?
Once bought, fuel costs should be reasonable. The diesels are the most economical, with the C300de hybrid version recording an official claimed figure of 217.3mpg and an all-electric range of 33 miles. The plug-in petrol hybrid gets 134.5mpg and 19 miles of electric range, while the C300h diesel hybrid has a claimed figure of 78.5mpg.
The most popular model, the C220d, can claim 70.6mpg in some versions – almost a match for the C200d’s top score of 72.4mpg. The C250d is the least economical diesel at 61.4mpg.
The C200 petrol-engined car can produce a claimed figure of 53.3mpg, depending on wheel and tyre size. Even the high-performance C43 and C63 seem to have reasonable numbers at 35.3mpg and 34.5mpg, respectively.
However, all figures those are based on the older NEDC tests. Under the more stringent WLTP tests, the C200d averages 61.4mpg, the C220d 55.4mpg, the C300d 47.9mpg. The petrol C180 gets 43.5mpg, the C200 44.1mpg, the C300 40.4mpg, the C43 30.4mpg, and the C63 dropping to just 28.5mpg.
All of the hybrid and plug-in hybrid models produce less than 100g/km of CO2 and qualify for free road tax (provided the example you're looking at was registered before 1 April 2017). Then follows the C200d at 101g/km and the C220d at 104g/km. The C250d isn't as good at 117g/km, but it'll hardly break the bank.
Neither will the C200 petrol 123g/km hurt your wallet too badly. Mind, the 183g/km of the C43 and 192g/km of the C63 might seem like a lot, neither are horrendous given the performance on offer.
Car tax (VED)
Cars registered before the tax changes of 1 April 2017 came into force will pay the annual car tax (VED) according to CO2 emissions, while those registered after that date will pay a flat rate, currently £150 a year. Be warned, though, if your C-Class cost over £40,000 new, it will then attract a supplementary luxury car tax. To find out more about the current road tax costs, click here.
Servicing costs for the C-Class can be expensive, as can replacement parts, but you are able to split them into monthly payments to soften the overall costs. Two services for a C-Class that's less than 12-months old would be £816, while anything older is £912. For comparison purposes, the same number of services for an Audi A4 would be £468 for one with an engine of less than 2.0-litres, or £594 if it happens to have something bigger.
