In terms of environmental impact, the 1984 Grand Marquis Wagon produces approximately 555 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this Grand Marquis Wagon has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,750, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $8,000 over a 5-year period.
