Same here. '17 X5M Individual w/ Dinan S2. In stock form it out performs every SUV in the current segment. Upgraded and dialed in there isn't anything better as a whole. The fastest and "sportiest" RRS/RR do not even come close to similar handling or even in the tech department.
Agreed it will blow anything away on the street. Not so much off-road where the RRS SVR would easily walk away. Again, complete package of do anything, SVR wins simply because of the off-road column. I do think the Supercharged V8 also takes the win in the sound category as well. M sounds good but not quite as good, stock to stock, IMO. Of course M is easier to add more power. Will be interesting to see if the new X5M gets air suspension or not. As stated, it could make this comparison even closer.
That said, I have always been the biggest fan of the iDrive system but my vehicle continues to not be able to play music from my iPhone. Plugged in, blue-toothed, none of it works. It either shows 20 songs and that's it or it skips around like a scratched CD. Plus, mine has goes in the shop every other month to have something replaced. Might as well be a Land Rover product!
Always said an LR4 with iDrive, RRS Sway system and BMW 5.0i / RRS V8SC would be an awesome vehicle. SVX comes pretty close to it. Doesn't have to have the most power, just more power than the SCV6. Don't understand why there isn't an option to get the 380hp version to be honest. That seems to me like an easy box to check.
