I just came out of an M5. This X5M is better. It handles shockingly well despite being an SUV. It telegraphs its limits better than the M5. The interior is superb. The iDrive and Bang and Olufsen stereo are wonderful. BMW has done a great job in moving the iDrive platform forward. The level of voice control over various functions has improved considerably over my '14 M5. Fit and finish have been excellent and no complaints. When you combine the performance and technology of this vehicle with the quotidian practicality of how much it can haul you will really want to consider it if in the market for a 5-series/E-class/S6-7 Audi.
