Infiniti Q50
The Infiniti Q50 is a sleek, handsome executive saloon that was Nissan’s luxury division's attempt to challenge the BMW 3 Series and Mercedes C-Class. It offered a high level of standard equipment, a comfortable ride, and uniquely aggressive Japanese styling. In the UK, it struggled to gain a foothold due to the dominance of German brands, making it a rare and depreciated used buy. The most controversial feature was the "Direct Adaptive Steering" (steer-by-wire system) on certain models, which felt artificial to driving enthusiasts. Reliability is generally robust, especially the Mercedes-sourced 2.2-litre diesel, making it a left-field bargain for buyers wanting a distinctive, reliable executive cruiser.
