The stick shift hasn't yet gone the way of the passenger pigeon and the dodo, but it's definitely an endangered species. As of August 2013, just 3.9 percent of new cars sold for the year had manual transmissions.

Cars with stick shifts and clutches have their ardent defenders, but some of the reasons they cite for the superiority and desirability of manual-transmission vehicles aren't supported by facts. Here are five myths about stick shifts:

1. Manual cars always get better fuel economy than cars with automatic gearboxes.

In the past it was pretty much a given that vehicles with manual transmissions would be more fuel-efficient than their automatic counterparts. But as automatics become more advanced and gain additional gears (eight-speed transmissions are fairly easy to find), they are often now overtaking manuals in terms of fuel economy.

For an example of when the myth is based in reality, there's the fuel-sipping 2014 Chevrolet Cruze Eco. The manual version of this small Chevy gets 33 mpg combined (28 mpg in the city/42 mpg on the highway). Equipped with an automatic transmission, the Eco is slightly less fuel-efficient: 31 mpg combined (26 city/39 highway). The manual will cost you about $100 less per year in fuel, according to fueleconomy.gov.

With the 2014 Ford Focus, it's the six-speed automatic version that performs better, getting 31 mpg combined (27 city/37 highway). If you spring for the Super Fuel Economy option package, which also uses the six-speed automatic transmission, fuel economy rises to 33 mpg combined (28 city/40 highway). A Ford Focus with a conventional manual transmission can't match the automatics. It gets 30 mpg combined (26 city/36 highway).

There are other examples as well. For the 2014 Versa, Nissan actually offers three transmissions: a five-speed manual, a four-speed automatic and a continuously variable transmission (CVT). The manual and automatic get the same combined fuel economy (30 mpg), but the CVT blows both of them away at 35 mpg combined. And it's not just economy cars where you can find this trend: A 2013 BMW 328i sedan will get the same combined fuel economy (26 mpg) whether you opt for the manual or the automatic transmission.

2. A car with a manual transmission costs less than the same model with an automatic.

In most cases, the manual version of a car will indeed cost less, but in some instances, it's the same price as an automatic. Examples include such GM vehicles as the 2013 Buick Regal GS and the 2013 Cadillac CTS-V. Among BMWs, the manual is often the same price as the automatic. And you can't always get the car you want with a manual transmission: 67 percent of 2013 model-year cars came only as automatics.

3. The coolest sports cars only come with manual transmissions.

This depends on your definition of "cool sports car." The seventh-generation 2014 Chevrolet Corvette Stingray and many flavors of the 2014 Porsche 911 offer a choice of transmission types. But if your choice is the 2014 Porsche 911 GT3, which Edmunds editors call "the baddest Porsche on the block," you can only get it with Porsche's dual-clutch automatic transmission. The same goes for the 2014 Jaguar F-Type the 2013 Maserati GranTurismo,the 2013 Lamborghini Aventador and the 2013 Ferrari F12 Berlinetta.  All come with automatic transmissions. No manual gear-shifting ballet for you.

It's no loss, says Ken Hill, a professional racer, driving educator and vice president of operations for Automotive Adventures in Bellevue, Washington. "Some people are stuck on the mindset that a driver is faster with a manual box," Hill says. But there's a reason why some major performance-car manufacturers, including Ferrari and Jaguar, no longer offer traditional manual transmissions, he says. "They just aren't as good."

4. If your dream car comes with a standard manual transmission, you can always get an automatic as an option.

Like the previous assumption, this one isn't true either. A small group of cars, mostly sporty models, only come with manuals. The list includes the Audi TT RS, the Fiat 500 Abarth, the 2014 Ford Focus ST, the 2014 Ford Shelby GT500, the Mazdaspeed 3 and the Volkswagen Golf R.

5. Teenagers really, really want to learn to drive stick shifts.

Not so, says Hill, who teaches teen driving programs. Because there are so few manuals out there, many drivers who have just earned their licenses don't get exposed to them, and so they have little interest in learning how to drive them, he says.

"It's a complication they don't need," Hill says. Just think of all the times you stalled out as you tried to shift a manual car in stop-and-go traffic. "Kids have the advantage of not being burdened with nostalgia." And as a result, he adds, "Ninety-plus percent are perfectly happy with the automatic they have access to."

The Theft-Deterrent Theory: Myth or Reality?

There's one argument in favor of stick-shift cars that doesn't have a ready true-or-false answer. The theory is that because fewer people know how to drive stick shifts these days, cars equipped with them are less likely to be stolen.

Frank Scafidi, director of public affairs for the National Insurance Crime Bureau, which tracks car theft trends, says he's not aware of any data to support or refute that idea.

"Some thieves might be thwarted in their attempt to steal a car with a manual transmission, since many thieves possess varying levels of intellect," Scafidi says. "That very personal element is also a factor in the degree of expertise necessary to overcome some of the more sophisticated security systems.

"Most car thieves are just not that swift and therefore resort to stealing older, easier targets," Scafidi says. "But there are those in the car-thief ranks who are quite capable of making off with anything that they intend to steal."

Stick-Shift Realities

When the argument in favor of the stick shift is based on how much fun it is, it's undeniable. Stick-shift savvy also comes in handy if you're a passenger in a manual-transmission car and the driver is incapacitated in some way. And it's helpful if you're stuck somewhere and the only car available is one with a stick.
