I'm new to this forum and I'm interested in the new F10 535i in Malaysia. Since the launch, I have not seen many of it around. In fact, I've only seen 2 units so far and its parked infront of hotels. My questions are:1. Is the N55 engine really suitable for Malaysian fuel? Will you encounter long term engine damage from using RON 95 in Malaysia.2. Does the current batch of 535i have any other problems?3. I've seen grey imports selling for under 450k. I understand the level of trim and finishing may be different from the official dealer. Are there any other differences?The price difference betw grey import and BMW Malaysia is almost 200k. Price difference from 528 and 535 also about 150k. Anybody here thinks its worth paying that premium for the N55 engine? Is it worth the extra power?
