16 2013 Mercedes-Benz C Class Saloon

The Mercedes-Benz C Class diesel saloon with manual transmission was the UK's fastest selling car in May, according to Auto Trader.

Auto Trader trade solutions director Karolina Edwards-Smajda said: “In the three months since Auto Trader started publishing these figures, models in the top ten have consistently aligned closely to their optimal retail price position. That should resonate with every dealer because the same principle applies to each car on a forecourt. If you want to sell quickly, price to the retail market - that’s the market as it is now, not as some might suggest it could, should or might be.

“Of course, these charts are high level, but the science behind these figures can support every dealer on every forecourt. Pricing, demand and speed-of-sale data powers the same intelligence that works on a targeted micro-level and is instantly available to any retailer. It helps them work out what should be paid for the right car in the right location to maximise profits, as well as the price to sell it for to boost speed of sale.”
