Lovely cars, but have a google for snapped crankshaft 3.0 sdv6.
One of the problems with the 2.7 and the 3.0 engines, is their low oil capacity even when the oil is at max mark on the sitck/gauge, and as usual people dont lift their bonnets to check anything, the oil gets low especially if it has not had the turbo oil return pipe mod done, and you can guess the rest!
The service intervals are also way to long.
