Its not a matter of trust, I was a Bentley service advisor for years and I'm only speaking from experience. They are pretty reliable as far as getting from point a-b but there are so many bells and whistles that something is always failing, even if it is just the power mirrors, third brake light, or the infotainment system. Each of those repairs costs over $1k and if you don't stay on top of them you will end up with a car that drives but nothing else works. Also, the W12 is a pretty "special" engine, the way its packaged there is very little room to access most parts. If you need to do something simple like change the serpentine belt, you have to remove the front bumper, radiator, condenser, oil coolers, and core support just to get to it. Not only that but there is no Hanyes, Chiltons, or Alldata manual for these cars, its very difficult to come by helpful information regarding diagnostics and repairs and working on them is far from intuitive. The reason the cars depreciate so hard is because the cost of owning and maintaining an older Bentley is nearly the same as purchasing and making payments on a new one.
