I looked into this a while ago after getting kinda sick of having to do work on my E53 all the while. It turns out the E70s are just as hilariously unreliable.

I'd only get one if it was
- Very well priced
- Came with an excellent aftermarket warranty that included 24/7 roadside assistance for when a poorly designed plastic part shears off in the middle of the mountains as night falls
- Was my secondary (or even tertiary) vehicle as it will inevitably spend weeks or months in the shop
