E39 540 Sport

Are you talking auto or manual? You'll be hard pushed to find a 540 manual.
The major failing with the V-8s is the steering and overall balance. They use old fashioned recirculating ball steering rather than the rack and pinion of the sixes. And the weight distribution isn't as good.
Reliability tends to be worse as well. Not with major components, though.
