Buying and owning

Costs, equipment, reliability, safety and security

Few buyers will choose to pay for either car in one lump sum but, if you do, the GLC will make a £3620 smaller crater in your bank balance. That’s partly because it’s the cheaper car to start with, but also because Mercedes dealers are willing to cough up a discount. We weren’t able to haggle anything off the SQ5 at the time of writing.

Consider the total cost of ownership, though, and the GLC suddenly looks less appealing. Even taking into account the big savings you’ll get when buying, the GLC is predicted to lose you more in depreciation during the first three years and will cost you quite a bit more to service.

Forget the promise of 34mpg, too. In the real world, these turbocharged V6 SUVs are woefully inefficient, with the SQ5 falling just shy of 25mpg and the GLC only just scraping over that hurdle. So, if the idea of squirting £2500 into the fuel tank every 12,000 miles makes you raise an eyebrow, you might want to consider a diesel, after all.
