d: you can also go to 'volvoworld.com' and get into the 850 site to decode your VIN; they also have year-by-year info which model had which engine, etc., as well as the production runs for each year, chassis numbers (they do NOT all start each year with #1 and go to #200,000 in a year that produced 200,000 cars, for example: this gives you a pretty good way to figure out if yours is from the early, or late, production run. BTW, the engine number will not match the chassis number.) Good Luck. HNY, 2! --PD.
