RR Cullinan (preowned) experience and comments?

Does anyone own, or has anyone owned, this vehicle for any length of time?   I am considering a high mileage example as a next vehicle in a few years. 

Love the RR brand, love the Cullinan presence.  ZF8HP is as bulletproof as a German transmission can be.  

I don't know much about the V12 reliability reputation.   

I DIY almost everything.  Anything short of failed engine internals is in my scope.   I would do all fluids, filters and spark plugs as a get-to-know-you project.

How does this V12 compare with the MB M279 V12, reliability-wise? 

Any strange specifications such as oddball tire sizes, exotic brake packages (besides carbon), oil spec, etc.?

Thanks for any comments. 

I haven't had a Cullinan but I've had a Wraith and Ghost. Amazing cars, nothing rides or feels like an RR. Never had a single problem with either one, just routine maintenance though mine were both under 15k miles. Parts are reasonable for the BMW-equivalent ones, obviously if you buy anything from an RR dealer it's going to have the RR tax applied. You won't regret owning one.

Thanks. Did you replace brakes or tires on the Rollers? Any unusual steps to maintenance that are more involved than what is found on MB, BMW or Porsche vehicles?
