Engine Swaps
That said I've yet to encounter an issue and I also know most people who own these in the US and none of us have really had problems. Most issues the cars have are related to the base vehicle but stuff like coolant leaks etc just don't happen due to the totally different (no compromise/budget restriction) setup on the W12s.
Book times are also the lowest on the D4 for that engine, having worked on all versions other than the diesel I can also confirm as much. Air suspension is a great design on these and I've seen over 5 cars now with 200k+ miles without issues and the struts can be rebuilt unlike Lexus and literally every part is cheaper and easier to acquire. You also can always find the OE parts maker so you know the part is quality, on top of that you also have access to generic parts on the cheap if you want to save money.
A few guys in the UK forums actually discovered the factory seconds vendor for suspension compressors so instead of paying $1200 for an OE part you can get one for $125 with 2 year warranty and they actually work. Stuff like bay is common, I personally found some NOS PS pumps in Germany and had a relative buy them all for me. The W12 uses a unique PS pump that retails for over $1300 at Audi but in reality can be rebuilt using any D3-4 Gen vane pump internals, in my case I have 7 of them though lol!
Engine itself is fully forged and hand built, we have several guys overseas and two here who are in excess of 250k miles (one over 350k) with the only fixes being spark plugs. There is really no major issues at all, the only way you can really kill one is if you fill the oil incorrectly but I'll link that info if you get one.

The W12 is physically incapable of making as little torque as the LS460, even off idle it's producing more than the 460s peak. The difference when driving is the same as going from a V6 to the LS V8 in terms of effortlessness and just endless power at all and any RPM.
The 500hp is also total bull$#!% btw, my car made 443 all wheel HP stock......meanwhile my RWD LS made 310
