Verdict
At RM888,888, the Mercedes-Benz GLS X166 Facelift is RM111,000 cheaper and carries 680 litres of luggage, 325 litres more than the X167’s 355 litres. The newer Mercedes-Benz GLS X167 Facelift costs RM999,888, but its 362 hp/500 Nm 3.0-litre twin-turbo petrol engine cuts 0-100 km/h to 6.1 seconds, against 333 hp/480 Nm and 6.6 seconds. It is also 77 mm longer with a 60 mm longer wheelbase, and gets MBUX, 22-inch wheels and a four-year warranty. For a Malaysian family prioritising luggage space and outlay, the outgoing car remains the rational used buy.
