Right now, my answer to that question would be no. My 1999 V70 celebrated the end of it's warranty by having several expensive problems. The first is an A/C compressor that shuts off in hot weather. The talk on the brickboard is that it is caused by an overheat switch inside the compressor that craps out. Most compressors have this switch on the outside, so it is replaceable, but not Volvo. So, now I am faced with disabling the switch, with who-knows-what consequences if an overheat condition develops, or replacing a compressor that works fine except for a switch that is supposed to protect it.

Then my Electronic Throttle System warning light came on. Why any cars needs "drive by wire" instead of a cable operated throttle, I don't know, but this system consists of two parts, both expensive. I realize you are talking about an S80 and I'm talking about a V70, but I'm really talking about the way Volvo builds cars nowadays.

The worst part of all this is that Volvo has hidden the information that you would need to fix the car yourself. Most of the computer fault codes are only accessible to the Volvo dealer. Not even an independent mechanic can get at them. So, when the dealer decides your car is too old for them to bother with, or you tire of paying a dealer's hourly rate, you are screwed. What happens when the car needs some part replaced that has to be programmed by that dealer-only computer and it is old enough that they don't want to work on it? You're screwed.

All cars have computers and fault codes now. But not all cars manufacturers are as secretive as Volvo about accessing them or the manuals to deal with them.

If you are the sort of owner who plans to always take your car to the dealer anyway, then Volvo is an acceptable choice. But if you prefer independent mechanics, or you want to work on it yourself, then it is not the right car. Research the availability of repair information before you buy your next car. I know I certainly will.
