Have you ever seen an ugly car and thought to yourself, "What on Earth would possess someone to buy that?" The decision may have been out of the driver's hands. More often than not, the choices we make are dictated by our personalities. And for those of us who believe in astrology, our personalities are largely dependent on which stage of the Zodiac the sun travelled through the day we were born. Skeptical? Not everyone is.  In fact, a recent Harris Interactive poll reveals that 31 percent of Americans believe in astrology -- while another 18 percent think that there might be something to it.

Next time you're thinking about buying car, take a little help from the stars. Read on to discover the ideal vehicle for your sign.

Aquarius: Jan. 20 - Feb. 18
Smart Fortwo

An oddball at heart, the Aquarius prefers the unconventional over the traditional. To him or her, it's more satisfying to deviate from the pack and try something new than do what's typical and expected. In fact, Aquarius' thrive on their individuality -- which is why the Smart Fortwo complements them so well. This tiny two-passenger car features a peculiar design that looks like a cross between a clown car and a pea pod, but it's far from ugly. What's more, on the outside it looks as if it would be cramped, but its cabin is actually roomy and comfortable. And though it doesn't appear much stronger than a lawnmower, the Fortwo has enough pep to make city driving a breeze. An Aquarius couldn't ask for a more unique car.

Pisces: Feb. 19 - March 20
Chevrolet Volt

The Pisces exists in a state of limbo -- caught somewhere between the real world and their imagination. They do this to escape the harsh realities of everyday life. While such thinking can often lead to procrastination, it also allows the Pisces to empathize with the pains of others and conjure up solutions that may one day materialize. For these folks, only the extended-range electric Chevrolet Volt will do. Engineered to achieve superior fuel efficiency, the Earth-friendly Volt should net anywhere between 48 to even hundreds of miles per gallon, and can be charged by simply plugging it into a basic 120-volt wall outlet. It is, however, still in the conceptual stage of development. Though Chevy claims that the Volt will go into production in 2010, its deadline has been postponed in the past. That, however, shouldn't be a problem for Pisces -- as they're revered for their patience.

Aries: March 21 - April 19
Hummer H3

Self-absorbed Aries strives to always be the center of attention -- asserting an imposing, yet exciting, impression on everyone that they encounter. Though Aries can be overbearing at times, this trait fits them well, as they're strong and confident natural leaders. For this reason, the Hummer H3 is perfect for an Aries. Not only does its hefty size leave an imposing impression, but its squared-off military design exudes leadership. What's more, its strong off-road capabilities make it a thrilling performer ready for any adventure.

Taurus: April 20 - May 20
Ford Fusion

Valuing security over all else, the Taurus is simple yet attractive, subdued but strong, and predictable yet reliable. Like the Ford Fusion, the Taurus is a steady performer. As its name suggests, the Fusion fuses an array of assuring elements to create an everyday vehicle that's comfortable and easy to live with. From its pleasing exterior to its spacious interior, solid performance, and strong reliability, the Fusion leaves drivers satisfied. It's even an Insurance Institute for Highway Safety "Top Safety Pick" -- a plus for any sign of the Zodiac.

Gemini: May 21 - June 21
Chevrolet Corvette

While astrologists believe that the Gemini is too scatter-brained to pay close attention to fine details, they also assert that he or she is quick (both mentally and physically), as well as communicative and adventurous. As such, the Chevrolet Corvette is an appropriate vehicle for the Gemini. In line with the Gemini's superficial nature, the ‘Vette's iconic design looks both luxurious and menacing, but it's interior cabin falls short of the refinement found in other luxury sports cars. However, its Ferrari-like power and intuitive sports handling ensure no moment behind the wheel is ever dull.

Cancer: June 22- July 22
Audi A4 Avant

Cancers are a contradiction, taking comfort in security but always on the look out for something new and exciting. And while they may give the impression that they're quiet and composed, they actually have very strong personalities. Furthermore, nurturing is second nature to them -- so they always surround themselves with those they love.

Of all vehicles, the Audi A4 Avant matches them best. Its long list of standard safety features and excellent performance in federal government crash tests provide security, while Audi's Quattro all-wheel drive system ensures that it's capable of any adventure. And though power is the last thing one would expect from a station wagon, the A4 Avant outperforms many in its class. Combined with its comfortable yet luxurious accommodations for five, the A4 Avant is a Cancer's dream.

Leo: July 23 - Aug. 22
Lamborghini Murcielago

To the Leo, image is everything. Always wanting to make his or her presence known, the Leo strives to be the best and attract attention for it. In fact, Leos are always on the hunt for the flashiest, most expensive things in life. And while such taste can result in excessive spending, Leos find the price well worth it. For such a person, only a Lamborghini Murcielago will do. Equipped with a 631-horsepower V12 engine, this first-rate street demon blasts from 0 to 62 mph in just 3.4 seconds, and makes everyone who sees its wild design drool with envy -- perfect for the attention-seeking Leo.

Virgo: Aug. 23 - Sept. 22
Lexus LS

Virgos are perfectionists. While they may appear composed on the surface, inside they're constantly thinking of new and innovative ways to improve. The result is an exceedingly high level of fussiness -- which isn't always a bad thing. No car embodies such qualities as well as the Lexus LS. Outside, the LS looks modern and attractive, but doesn't stand out. However, inside it features a level of sophistication fit for its distinction as a super luxury car. The seats are comfortable and luxurious, the controls modern and intuitive, and the materials unsurpassed. The LS is definitely a Virgo's car.

Libra: Sept. 23 - Oct. 22
Chrysler Town & Country

Libras go to great lengths to ensure that family and friends are comfortable and satisfied in their surroundings. Artists at heart, they combine creativity with intelligence to ensure harmony for everyone. Following suit, the Chrysler Town & Country is engineered to seat seven passengers in a variety of arrangements that meet everyone's needs. In addition to traditional face-front seating, the Town & Country offers Swivel ‘n Go seats -- by rotating the second row to face the third row and erecting a table in between, they create a mobile family room. Stow 'n Go seating is another versatile option. This system allows the second- and third-row seats to fold flat for increased cargo room. Like the Libra, the Town & Country has everyone's best interest at heart.

Scorpio: Oct. 23 - Nov. 21
Mazda Mazdaspeed3

With the Scorpio, there's always more than meets the eye. On the outside they appear calm and collected, while inside they're brewing with intense passion and power. The effect is an air of mystique that surrounds them everywhere they go. In line with the characteristics of a Scorpio, the Mazda Mazdaspeed3 features an attractive, low-profile hatchback design. Yet under its hood is a 263-horsepower turbocharged I4 engine that delivers loads of raw, unadulterated power. Combined with balanced sports handling, the performance-tuned Mazdaspeed3 takes turns and twists better than many sporty cars. Indeed, Scorpios will appreciate the secret it keeps.

Sagittarius: Nov. 22 - Dec. 21
Saturn Sky

The Sagittarius is free-spirited, always optimistic, and would rather enjoy the present than dwell in the past or on the uncertainties of the future. Consequently, it's hard to pin a Sagittarius down -- as most find routines too boring to bother with. With such a flighty personality, only a sporty convertible will do. Case in point: the Saturn Sky. It's sexy, quick, and offers little room for extra passengers and cargo -- perfect for Sagittarius' dread of drama and baggage.

Capricorn: Dec. 22 - Jan. 19
Toyota Tacoma

Always a hard worker, the Capricorn sets goals and does what's necessary to achieve them -- no matter how tough the job. He or she is ambitious and business-minded, yet always practical. Fitting the bill, the award-winning Toyota Tacoma delivers exactly what the Capricorn needs. Its long truck bed, hefty towing and payload capacities, off-road capabilities, and rugged design make it the perfect workhorse. Add to that its impressive crash test scores and solid build quality, and the Tacoma just makes sense.
