Choose the 1984 Eldorado if its Cadillac identity, midsize body and eight-cylinder gasoline setup matter more to you than fuel economy. Budget around $4,200 in EPA annual fuel cost, and expect the highest consumption in urban driving. The 20-MPG highway rating is the more favorable number for regular road trips, but this remains a 16-MPG combined car. Its 555.44 grams-per-mile tailpipe CO2 figure also reflects the cost of running this older gasoline powertrain.
