Average
Very refined and quiet. Effortless performance from all engines. Hybrid GS450h is superbly refined. Stuffed with technology and equipment. Excellent crash test rating.
Not the smoothest motorway cruiser. Some reports of below-par cabin assembly. Alloy wheels can oxidise. No diesel in the range.
