Volvo 850 is a Car item that can be acquired through Grand Theft Auto and is the least expensive item (by sell price) that can be obtained from Grand Theft Auto crimes. It can be sold to (but not purchased at) the Torn Docks.
The Volvo 850 can be obtained through the "Steal a Parked Car" Grand Theft Auto crime. It is obtained about .13% of the time (or roughly one time for every 750 successes) from "Steal a Parked Car." 
The Volvo 850 cannot be found through city finds but can be traded between players.
