Our Verdict

It was a close decision when these two were new, with the Mercedes edging ahead thanks to it’s lower purchase price, inexpensive running costs and more generous equipment levels. However, it has been noted that the C-Class Coupé isn’t the most dependable used coupé you can buy, and when your car gets older and runs out of its manufacturer warranty, you’d like it to be at least reliable, otherwise you could be footing some large bills for repairs. And, as we know, Mercedes dealer servicing and maintenance costs can be quite expensive.

The BMW, on the other hand, should be the more reliable car to own, plus it has the better infotainment system and more space in the back for carrying adults. You might find the extra traction from its four-wheel drive system to be of greater use, too, particularly if you live in a rural area that suffers from poor weather. However, we’d still suggest you go for the standard rear-wheel drive car over this xDrive model, since it's cheaper still and should be on a par with the Mercedes in terms of running costs. As it stands, we’re giving the win to the BMW this time around, even though it isn’t our favourite version, because the 4 Series is still a great used coupé and one that you should be able to enjoy without heartache.
