There’s plenty of room for tall drivers to get comfortable and you don’t feel too close to your front passenger. There are only two seats in the back of the C-Class Coupé, but they’re quite sculpted and comfortable, so two average-sized adults will be fine for most journeys. It’ll be a bit of a squeeze to get past the forward-tilted front seat and under the swooping roofline, but access is no worse than key rivals. If you do regularly carry adults in the rear, it’s worth bearing in mind that both the Audi A5 and BMW 4 Series are marginally roomier.
Usefully, the back seats split and fold 40/20/40 to leave a smooth but sloped load bay, meaning you can load longer items – provided you can feed it through the narrow opening between the boot and rear passenger space. Again, the boot itself isn’t quite as big as that of a 4 Series or A5, but it is deep and practical enough considering this is the coupé class.
