Are you on the hunt for a bargain coupΓ©? 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, mainly due to the substantial discounts not yet offered on the other two.

The 6 GT’s comparatively decent value is a consistent theme. It’s the cheapest for company car tax over three years, by Β£1000 for 40% taxpayers over the A7, which itself is Β£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 its 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. They all get automatic emergency braking as standard, while the A7 and CLS also come with lane assist. Blindspot monitoring is optional on all three.
