Funnily enough I just bought two of these on epay. Both 2001s. The first had a bad transmission which was declared by the seller and factored into the price. However, These transmissions are VERY expensive ($4400 plus labour). I thought I would get a used transmission but discovered that this particular car came from a very narrow vin range and no used transmissions were available-I finally sold it to a Volvo mechanic for what I had into it.
I then bought a Cross Country version-one owner, Arizona car, lowish miles for $8500-nice deal except I have been waiting a month for the freaking title to be sent to me. A copy was faxed today so I know it exists but i cannot import the car into Canada until the US approves export and they need the title for that....
There are a couple of very good sites on the web for researching maintenance issues that provide cheap fixes if you know one end of a wrench from the other. The big issue with these cars is flushing the transmission system every 50,000km or so--something that is not mentioned in the service book! The fluid is special but don't for God's sake pay the stupid Volvo price. Toyota uses the same transmission and sells the fluid at a reasonable price-it is called Type 4 by Toyota but is made by Mobil and is type 3309 if you can get a Mobil dealer to sell to you. I used to be a service manager for Volvo, then VW/Audi/Porsche. Volvo makes very good cars-the paint finish is amongst the best you will find on any car but expect expensive maintenance-just the way they are....
