According to a recent study, just because you're rich doesn't necessarily mean that you flaunt it on the road.

The study, done by TrueCar.com, looked at the 10 best selling cars in the top 10 wealthiest zip codes, as determined by the IRS.

While some of the vehicles on the list are to be expected (BMWs and Benzes), many others may surprise you. In fact, half of the cars are non-luxury vehicles (and there's a hybrid!) and all but two cost less than $50,000.

Click through to see what America's rich and famous are driving today. It looks like these millionaires and billionaires aren't so different from the rest of us after all.

10. BMW X5

MSRP: $47,500 - $64,200
Invoice: $43,880 - $59,245
Fuel Economy: 16 mpg City, 23 mpg Highway

The big, luxurious BMW X5 SUV kicks off our list. It's not surprising to see that this vehicle is one of the top sellers for the wealthiest zip codes as it offers tons of luxury and safety features for the affluent family on the go. Plus, you get that coveted BMW badge in a very versatile form.

9. Toyota Camry

MSRP: $22,055 - $30,115
Invoice: $20,181 - $27,404
Fuel Economy: 25 mpg City, 35 mpg Highway

We aren't overly surprised to see the Camry on this list, given that it is one of the top-selling cars in the USA, period. However, with all of that money, we're wondering why the wealthy inhabitants of these areas aren't opting for something with a little more flair.

8. Honda Accord

MSRP: $21,480 - $30,030
Invoice: $19,667 - $27,465
Fuel Economy: 23 mpg City, 34 mpg Highway

Much like the Toyota Camry, the Honda Accord is among the best-selling vehicles in the country, period, so it makes sense that it's on the list. But, again, it's not what we would buy with that little extra pocket change.

MSRP: $22,495 - $28,495
Invoice: $21,133 - $26,749
Fuel Economy: 23 mpg City, 31 mpg Highway

This compact crossover is an excellent buy, with its great versatility, reliability and fuel economy. Americans from all classes appear to be picking this CUV in droves, as it has been a big hit with the wealthy and the population in general.

6. Volkswagen Jetta

MSRP: $15,545 - $28,200
Invoice: $14,923 - $27,072
Fuel Economy: 24 mpg City, 34 mpg Highway

We know that the wealthy tend to enjoy imported cars, but we're interested to see that the least-expensive German car is one of the most popular in these upper-class areas. The Jetta is a very capable sedan, but its interior features and exterior aesthetics leave something to be desired.

5. Toyota Prius

MSRP: $24,000 - $29,805
Invoice: $22,560 - $27,744
Fuel Economy: 51 mpg City, 48 mpg Highway

The Toyota Prius has become the car of choice for making the statement that says "I'm green" over the past couple of years. Since going green has been a fairly prevalent movement among the rich and famous, it makes sense that the hybrid would be high on this list.

4. Lexus RX

MSRP: $39,310 - $47,000
Invoice: $36,754 - $43,945
Fuel Economy: 18 mpg City, 25 mpg Highway

The Lexus RX is a luxurious crossover that comes with an abundance of standard and available features that is sure to make any driving experience an enjoyable one. It's a great vehicle, but it certainly doesn't come cheap, starting at just under $40,000. This is a stylish way to get the kids to soccer practice and the residents of wealthy areas love it for that.

Invoice: $32,876 - $57,967
Fuel Economy: 22 mpg City, 31 mpg Highway

The C-Class offers style, performance and, of course, that coveted Benz logo on the grille. Mercedes is one of the most sought-after brands by wealthy drivers, given that it is held in such high regard in popular culture and automotive circles alike.

Invoice: $33,760 - $43,970
Fuel Economy: 23 mpg City, 33 mpg Highway

BMW's 3 Series luxury sedan is a benchmark in the auto industry and is simply one of the best luxury cars money can buy for its driving dynamics and luxury features. People with disposable income know this and are buying up the venerable 3 Series in droves.

1. Mercedes-Benz E-Class

MSRP: $51,000 - $92,400
Invoice: $47,430 - $85,932
Fuel Economy: 20 mpg City, 30 mpg Highway

The car that the rich are buying the most is the Mercedes-Benz E-Class. The E-Class is another one of the best luxury vehicles available today. It's distinctive, super comfortable and great to drive. But it all comes at a hefty price. Starting MSRP for the most popular car in America's wealthiest zip codes is $51,000.
