Verdict
The BMW X6 is the rational Malaysian buy here: RM734,800 against RM999,888 for the Mercedes-Benz AMG SL, a RM265,088 gap before you even count annual road tax. The X6 is bigger, seats five, has a 580-litre boot and all-wheel drive, so it fits daily family use better. The AMG SL answers with 375 hp, 480 Nm, 0-100 km/h in 4.9 seconds and a 275 km/h top speed. Fast and expensive. The BMW is less dramatic, but far easier to justify.
X6
Pick the BMW X6 if you want the roomier, cheaper and more practical CBU hybrid SUV with five seats and a 580-litre boot.
AMG SL
Pick the Mercedes-Benz AMG SL if you want the quicker convertible, can live with four seats and prioritise 4.9-second pace over luggage space.
