If you don't think a Volvo belongs on this list, you haven't been in one of its models lately. The XC90 already has one of the best cabins in the business, but the Swedes' new $105,000 Excellence model is positively next level.
US Excellence models have four individual seats, but in other markets, Volvo has gone so far as to remove the front seat entirely for a Lounge model, clearing the room for a separate ottoman and NBA-spec legroom.
Starting at over $191,000, the V12-powered Mercedes-Maybach S600 oddly feels like good value compared to rivals from Bentley and Rolls-Royce. There's even a less-expensive S550 model that starts at $161,000.
So you say you're a captain of industry who likes to drive his or her own ship every once in a while? Fear not, we have just the ride for you. It's Porsche's redone-for-2018 Panamera, which promises to be an even better steer than its already-great predecessor.
When it comes time to hand Jeeves the key and slip in the back seat, you won't be disappointed. There's surprising room in back in long-wheelbase Executive models, with deeply sculpted seats and plenty of amenities.
You didn't think you could get through a list of most-luxurious car seats without a Rolls-Royce on the list, did you?
This particular car is one of 20 Bespoke Serenity Extended Wheelbase models. It's indicative of the level of custom hand-crafted work Rolls-Royce will happily let you specify if your wallet is big enough.
To give you an idea of how much work goes into one of these wild Serenity bespoke models, the Asian robe-inspired flowers are hand painted directly onto Chinese silk. Rolls says the process takes some 600 hours of work per panel.
