Well, depending on the car's condition, what one would usually now referr to as 'carfacts' as I believe the commercials go, if you are looking to offload it as scrap or not, then I would need to have a better idea of its condition. If you are asking for some manner of an average, that I can find for you easily enough. Though as a personal recommendation, you should probably try looking into used car magazines, they often have websites that have lists of cars for sale as well as cars sold to give an average guide to prices, allows you to see common problems and what to expect in so far as wear in your vehicles over time, but as far as the average resale value of the Volvo XC...Well, depending on the year that it is and if we are taling the XC90, I am seeing values from as little as $4,000 to as much as $20,000, depending on year and condition.
