Consider yourself forgiven if you can't immediately distinguish the revised Mercedes E-Class from the car that's been around for four years. Unless you know your Benzes backwards, the changes are hard to spot. Recent tweaking of the exterior and interior styling won't threaten the current model's resale value and the big changes are hidden away. Like what? Five new or revised engines, for a start. There have also been small but significant chassis changes and a bundle of new safety kit has been introduced. There's also an optional intelligent lighting system that automatically varies beam pattern according to location and speed. To some extent, you're paying for new stuff you hope you'll never use, such as Neck-Pro anti-whiplash head restraints, or the Pre-Safe system that shuts windows, moves front seats to the safest position and tightens seatbelts if a crash seems likely. On a cheerier note, you get new upholstery and trim ­materials, better climate control system, four-spoke steering wheel and colour choices. E-Class and other fans will be impressed by improved driveability, handling and safety, and the promise of better reliability.

On sale from next month - expect to pay from £27,525.
