Had my S80 T6 for 18 months from 22K to 40K miles. During that time, the following failed or broke: upper strut mounts (2), oxygen sensor, mass flow sensor, motor mount, lower control arm, strut assembly, front brake rotors, ABS control unit, turbo oil return line, dashboard clock, ignition switch, turn signal switch, headlight assembly, exterior trim piece, door trim piece, etc., etc. Additionally, when I sold it, one of the turbos was blowing oil and the transmission shifts had gotten mushy (neither of which the dealership was willing to correct). Other than that, it was the best car you could ever own. It was fast, handled great, and was very comfortable. It also got about 20 mpg.
Beautiful paint (moondust), exterior styling that grows on you, strong performance with descent gas mileage, nice ride, solid feel, THE MOST COMFORTABLE SEATS EVER if you are over 6 feet tall, some exclusivity.
Truly comical reliability (we started taking bets at my office on when and what would break next), horrific resale value (how many cars are you aware of that go from $48K to $12K over a period of 5 years).
