In a period of 18 months the following failed: ignition switch, oxygen sensor, mass flow meter, motor mount, upper strut mount, headlight assembly, brake rotors, ABS control unit, turn signal assembly, turbo oil return line, front strut assemblies (2), door trim piece, turbo oil seals, etc. It also had a nasty habit of throwing black brake dust from the front rotors down the side of the car. The really bad part is that if it had been even somewhat realiable, this would be an unbelieveable car. It is nice to look at, very comfortable, relatively easy to work on, and it is very cheap on the used market (probably due to the horrible reliability).
Excellent seats for tall people, fast, comfortable, and roomy, really not many cars that compete with it in this price range.
This car has comical reliability, we literally had an office bet on what would break next, DO NOT even think about an S80 without buying an extensive warranty; you will see that everyone who was happy with their's in the reviews had one.
