In terms of environmental impact, the 1988 Century Wagon produces approximately 423 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 Century Wagon has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $2,850, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $3,500 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.
