Cons

Mercedes-Benz GLE

OM651/OM642 diesel: timing chain and AdBlue/DPF need checking

Early 1.6 THP carries timing-chain risk

Driving experience

Mercedes-Benz GLE

Big, comfortable and more truck-like than the GLC. The W166 rides with a soft, absorbent gait, especially on AIRMATIC, steers lightly with little feedback, and feels genuinely large and commanding from behind the wheel. 4MATIC is standard and gives confident traction, though this is a comfort-first car rather than an agile one. The M276 V6 petrol is smooth and strong, the OM642 diesel is the towing and distance workhorse, and the 500 e plug-in covers short trips on electric power. The 7G/9G automatic is smooth. It is a spacious, comfortable large SUV built for comfort, space and towing, not for keen driving.

Peugeot 3008

The T84 is the 3008 that put Peugeot into the crossover game, and it drives more like a tall hatch than an SUV. Built on the PF2 bones shared with the 308, it stays reasonably light, so the front axle turns in cleanly and the raised body adds visibility without making the ride busy. The high-set driving position and big glass make it feel solid and easy to place, while most versions ride on a comfort-tuned rear that irons out broken tarmac. The 1.6 THP is eager, the 2.0 HDi pulls strongly and quietly, and the 6-speed automatic shifts without fuss. The HYbrid4 adds electric drive but is more complex. It is a comfortable, easy crossover, not a sporty one.
