you sure or not? can you handle the issues? because BMW is famously known for its sensors and other issues such as brake sensors, ACE (dashcam), AGM battery and fuel pump. even though the problems are easy to fix but it will popup in your screen several times a year. in addition, if your car breakdown, you must use a flatbed to carry the car. this is no problem cuz you will have BMW mobile service available at your convenience. you can't simply tow using a regular tow truck cuz this car is an xDrive (meaning it's an AWD). you get what i mean? also, did you know the aftersales service for M series are far more expensive than both regular BMW and Mercedes? but yeah, it's your money so do whatever you want. cheers!
