On the plus side, after production moved to Germany, these V12s became very reliable, not having any major issues. But on the negative, they like to eat ignition coils faster than most cars. Likely due to the coils buried deep under the intake manifolds with absolutely no air circulation. And this, once every 30k mile service is a major pain in the butt. If everything goes perfect (very unlikely given how old these cars are now), it takes about 6 hrs to R&R the coils and spark plugs.
