In order to do a new car comparison, it is important to compare apples to apples. In other words, it would be foolhardy to compare SUVs to compact cars. Any new car comparison should take similar classes of cars and look at how they stack up against each other.

For instance, the Volkswagen Golf, Dodge Caliber, Kia Soul Exclaim, and Mazda 3S Sport are all around the same price – $17,000 to $19,000. While they are largely similar cars, they differ in some respects. For instance, the Golf has a 2.5 liter engine while the Kia and the Mazda have only 2 liter engines. The Exclaim Soul and the Sport also have significantly lower displacement. The Kia doesn’t have front side airbags while the other three vehicles do.

There are similarities and differences at the other end of the spectrum as well. Two very similar cars are the Rolls Royce Ghost and the Mercedes Benz S-Class. But, the prices of the two cars are not very similar. The Ghost starts at $245,000 while the S-Class starts at $133,000.

The SUV market also shows the differences between vehicles. Let’s take a look at four SUVs ranging in price from $19,000 to $22,000: the Kia Sportage, Suzuki Sportback, Nissan Rogue, and Mitsubishi Outlander. One difference is the horsepower with the Sportage having 140 horses and the Rogue with 170 horsepower. They also differ in how many miles to the gallon they get with the Sportage getting only 25 while the Sportback leads the pack at 30 miles per gallon on the highway.

When you do a new car comparison, make sure you are comparing apples to apples. A Mini Cooper is not in the same class as a minivan and shouldn’t be treated as such.

If you are looking for a cool new cars, I suggest you head on over to Edmunds.com for some great shopping. Don’t reprint this exact article. Instead, reprint a free unique content version of this same article.
