Verdict
These are radically different RM1 million Mercedes choices. The AMG SL is the sharper Malaysian weekend car: 375 hp, 4.9-second 0-100 km/h pace and a RM376 annual road tax, while its 1,810 kg kerb weight is 575 kg below the GLS. The GLS answers with seven seats, a 355-litre boot and all-wheel drive, plus a 90-litre tank for longer family runs. Its 500 Nm arrives from 1,600 rpm, but 6.1 seconds to 100 km/h confirms that carrying seven people and much more metal is the priority.
AMG SL
Pick the Mercedes-Benz AMG SL if open-top driving, 4.9-second acceleration and lower annual road tax matter more than rear-seat and luggage capacity.
GLS
Pick the Mercedes-Benz GLS if you need seven seats, a 355-litre boot, all-wheel drive and proper rear-cabin amenities.
