Last week, , and you delivered, albeit a bit slower because I assume hypermiling was involved. Here are the best gas-saving cars on eBay, for less than the price of your average new car's down payment.

Here's a car that takes the reliable and not-at-all unpredictable handling of a Reliant Robin, the impeccable quality control of Chinese manufacturing, the sheer speed of an early all-electric drivetrain, and the timeless good looks of tiger stripes on the exterior and interior. .

9. 1988 Subaru Justy

Before Subaru made rally stage destroying, all-wheel-drive powerhouses, it made small, fuel efficient hatchbacks to make ends meet. The Justy was one of these cars. Honest, cheap, dependable, with a party trick - nearly 40 miles per gallon, more than a decade before the Prius came to the party. .

8. 1995 Saturn SL1/SL2

Saturns, in general, were revolutionary in their day. . A good friend of mine had an early SL1, with the single overhead cam 1.9 liter four cylinder engine throughout college. Although it was a super-dependable mode of transportation, the manufacturer had the audacity to put a "performance" switch on an 85-horsepower car. At least it was great on gas.

7. 1988 Cagiva Tamanaco 125cc

Sometimes the most . I'll let explain:

The most efficient way to travel is in a straight line, A to B directly. The ideal transportation makes this feasible. . You do not need to make turns or even substantially alter your rate of travel. You find your bearing, apply throttle, and you'll get to your destination. Seriously, in terms of any obstacles you are thinking of, what does your little subdivision have that, say, Africa does not? Paris-Dakar, bitches. This bike has it. It's also really cute and the engine sounds like it can make the grade and probably out-mpg a Prius.

6. 2003 Toyota Prius

. Although it is somewhat synonymous with the most disconnected driving experience one can have, it has the running costs of a manual pencil sharpener and will run forever if taken care of properly. It can out-mileage nearly any gas-powered car to this day, and for this price, that's no small feat.

5. 1997 Honda Civic CX

No dependability/reliability/fuel-mileageability challenge would be complete without at least a nod to the ubiquitous Honda Civic CX. This barebones hatchback is what the Eastern bloc wanted to make during the Cold War but couldn't, because capitalism just does everything better. . A great buy for anyone looking for a cheap running means of transport.

4. 2000 Volkswagen Jetta TDI

. If you ever drive one, you'll understand that this just makes sense and you'll wonder why all cars don't run on small diesel engines. This Jetta looks like it's been murdered out on a budget, with rare non-options such as roll-up windows and cloth interior installed, with the added benefit of nearly 50 mpg. It's easy to work on and actually not much of a slouch in the performance department. A solid deal for anyone that wants to run on used vegetable grease.

3. 1994 Geo Metro 3-cylinder

This car does not play games, and it doesn't pretend that it's something it's obviously not. There aren't any textured panels simulating carbon fiber or leather. It's nothing but molded plastic, rubber, and cloth on the inside of this car. It can fit 5, but only just. . It's like a frugal honeybadger - it's cheap and it just doesn't care.

2. 1990 Honda CRX HF

The Honda CRX HF is the car manufacturer's best attempt at making a car that runs on nothing. This car was rated by the EPA at 55 mpg, but with hypermiling techniques and a little homemade aero, you could bump the savings up nearly 100 percent. I'm confident that if you put a big enough fuel tank on the inside, it could make it across the country without refueling once. .

1. 2002 Honda Insight

. It has aero covers on the rear wheels, has a hybrid gas-electric drivetrain, and despite being 12 years old, it looks futuristic enough to be driven by Tom Cruise in his latest sci-fi flick. How many MPG? Up to 100, with hypermiling techniques. That's absolutely insane, and you still get the same Honda reliability, just for much, much less money. If no one buys this, I just might.
