Of course your wallet hurts every time you have to fill the car up. Nevertheless, in these trying times we must always remember the words of Fernando Lamas: it is better to look good than to feel good. Cars That Matter has put together a list of classic automobiles that get anywhere from 21 to 48 mpg, which means you can look good while you save money.

The heaviest drinker is the Datsun 240Z, just cracking into the twenties. But plenty of cars hover around the 30 mpg mark, like the Lotus Europa, Alfa Romeo Giulietta Spider, and Fiat X1/9. If you want to crack the big four-oh, you've still got choices: BMW Isetta and Honda S800. And the Crosley Hotshot will get you a miserly 48 mpg.

If anyone were to come along and do an updated version of Dire Straits' "Money for Nothing," the could change the background vocal from "I want my MTV" to "I want my MPG" or "I want my low Cd." Coefficient of drag, that is. Carmakers are taking every step they can, starting with aerodynamics, to give cars better gas mileage right now while they wait for more substantial technologies to come online in the near future.

But the tweaks don't stop with aero finessing. The 2009 Dodge Ram spent 200 hours in the wind tunnel, and it also received tweaks to its ECU, which means it spends more time in its cylinder cutoff mode. That, plus eighty pounds of weight savings, adds up to one more MPG on the EPA sheet. Said Ford's Derek Kuzak, "We need to treat every joule of energy in a vehicle like a precious commodity."

When the C-Class predecessor launched, it was known as the 190 and carried a four-cylinder powerplant underhood. Mercedes is now considering a return to four-pots in the U.S. market as the price of fuel continues to soar. MBZ is reportedly already testing a 1.4-liter carrying a supercharger, which is strange when you consider there's already a 1.8-liter blown four-cylinder on sale in Europe. The C180 Kompressor seems like it'd be the easy way to get fours back into the U.S. lineup, but Mercedes must have some other ideas driving the decision to develop the smaller 1.4.

Readers of London's Sunday Times kept telling the auto reporters that the official mileage numbers for the Prius were overstated by about 15 imperial mpg. Intrigued, the Times decided to test things out by running a Prius against a BMW 520d with regenerative braking from London to Geneva, a 460-mile trip. Then they added 100 miles of urban running to give the Prius a chance to recover ground on its proper turf.
