The "Cowboy Cadillac" has been in production since 1935, making it the longest-lived automotive nameplate still on the road. That's a testament to its utility -- carrying up to nine passengers off-road -- and its profitability -- right at the top of GM's income statement. All that capability, however, requires nearly three tons of automobile powered by a V-8 engine that delivers only 15 miles per gallon in the city/21 mpg on the highway. With its 31-gallon fuel-tank, each Suburban fill-up will run you $100 or more.
