Mercedes-Benz set the trend for four-door coupés with the original CLS. Does the latest model continue to lead the way ahead of its German rivals?...

Are you on the hunt for a bargain coupé? Then run for the hills, because the brochure price of any of these three might induce a coronary. That said, the 6 GT is cheapest by a margin, both before and after discounts.
The 6 GT’s comparatively decent value is a consistent theme. It’s the cheapest for company car tax over three years, by £1000 for 40% taxpayers over the A7, which itself is £1000 cheaper than the CLS. And the cheapest car to lease? Again, it’s the 6 GT, by a massive margin over the A7 and CLS. Least expensive for PCP finance? Yep, you guessed it: still the 6 GT.
Officially, the 6 GT is the most fuel efficient, but only just; a couple of miles per gallon separates it and the least efficient CLS.
All three come well equipped; adaptive LED headlights, heated front seats and climate control are standard across the board. You also get full leather trim in the 6 GT and CLS, and part-leather and Alcantara in the A7. But again, the 6 GT outshines its rivals by including a standard panoramic sunroof, metallic paint and power-folding door mirrors.
Many of the 6 GT's options are cheaper, too, and are available individually, rather than as part of pricey option packs, as they are on the A7 and CLS.
Only the 6 GT has a Euro NCAP crash rating; it received five stars. However, each car gets automatic emergency braking as standard, while the A7 and CLS also come with lane assist. Blindspot monitoring is optional on all three.
