BMW E60 M5 (2005–2010)

Power

500 hp

Engine

5.0-liter naturally aspirated V10

The E60 BMW M5 remains an absolute anomaly in the automotive world. It looks like a regular 5 Series from that era, but underneath its understated sedan body sits a high-revving 5.0-liter naturally aspirated V10 engine making 500 hp and 383 lb-ft of torque. This Formula 1-derived powerplant revs to a staggering 8,250 rpm, with an exhaust note that sounds ready for war.

It is a four-door luxury sedan capable of keeping up with supercars from its time. This car offers an experience that few others can replicate. But this is a BMW with an exotic engine, so you need deep pockets to keep it going.

BMW E63/E64 M6 (2005–2011)

Power

500 hp

Engine

5.0-liter naturally aspirated V10

If you love the mechanical soul of the E60 M5, you can have the same experience in a coupe or convertible. The E63/E64 M6 shares the same legendary S85 5.0-liter V10 engine, but in a lower, wider, more aggressive body style.

Despite having the same powertrain and a sportier body, these models are often cheaper than an equivalent M5, with many examples listed below $20,000. Spending $20,000 to $30,000 should at least get you a good M5 or M6.

Porsche Panamera Turbo (2009–2012)

Power

500 hp

Engine

4.8-liter twin-turbo V8

The Panamera was Porsche’s entry into the luxury four-door sports-sedan market and, just like the Cayenne, it opened a whole new market for the brand. As with any Porsche, there are many trims, but the one you want is the Panamera Turbo. This executive sedan comes with a 4.8-liter twin-turbo V8 making 500 hp and 516 lb-ft, mated to Porsche’s lightning-fast seven-speed PDK dual-clutch transmission.

This rocket uses all-wheel drive to sprint from 0 to 60 mph in under four seconds. It combines genuine Porsche sports-car dynamics, high-speed stability, and an ultra-luxurious cabin at a fraction of its original $130,000-plus price tag.

Jaguar XKR

Power

510 hp

Engine

5.0-liter supercharged V8

If you want serious performance paired with timeless British elegance, the Jaguar XKR is hard to beat. With an all-aluminum body designed under Ian Callum, the XKR packs a 5.0-liter supercharged V8 delivering 510 hp and 461 lb-ft of torque. It has effortless grand-touring speed, a beautiful exterior, and an interior wrapped in fine leather and aluminum, making it one of the most stunning power bargains on the road.

It already has a great exhaust note, but fit an exhaust to one and it will produce one of the nastiest sounds you will ever hear.

Ford Shelby GT500 (2007–2012)

Power

500–550 hp

Engine

5.4-liter supercharged V8

Carrying the iconic Shelby badge, the S197 GT500 is the definition of pure Mustang muscle heritage. There are two generations of these cars, both with 5.4-liter supercharged V8s. The 2007–2009 S197 I made 500 hp and 480 lb-ft of torque and easily falls into this budget in the mid-$20,000 range.

Later 2010–2012 models received a redesign and an updated aluminum-block V8 pushing around 550 hp and 610 lb-ft of torque. You will have to search a bit harder to find these under budget. Mated strictly to a Tremec six-speed manual transmission, the Shelby GT500 is a straight-line weapon with classic retro muscle looks, an addictive supercharger whine, and endless customization potential.

Mercedes-Benz E63 AMG (W212) (2009–2013)

Power

518–550 hp

Engine

6.2-liter naturally aspirated V8 / 5.5-liter twin-turbo V8

Depreciated AMGs make great performance bargains, and the W212 E63 AMG is an executive autobahn machine at its finest. Early models had the legendary high-revving 6.2-liter naturally aspirated M156 V8 producing 518 hp and 465 lb-ft of torque. Later models, from 2011, transitioned to a 5.5-liter twin-turbo V8, which initially made 518 hp and 516 lb-ft of torque.

Models with the Performance Package push up to 550 hp and 531 lb-ft of torque. Whichever engine you choose, the E63 is a luxurious five-passenger car with muscle-car acceleration tucked inside a classy German sedan layout.

Mercedes-Benz CLS63 AMG (2011–2013)

Power

518–550+ hp

Engine

5.5-liter biturbo V8

This is the most beautiful CLS and is perfect for drivers who prefer head-turning four-door-coupe styling, undeniable presence, and everyday usability. But this beauty has a beast underneath. It is powered by AMG’s monstrous 5.5-liter biturbo V8, the same updated engine used in the later E63.

This sweeping sedan churns out anywhere from 518 to more than 550 horsepower, depending on the performance package. Its sloping roofline, wide stance, and muscular exhaust tone make it look and feel like an exotic cruiser that should cost three times its current market value.

Bentley Continental Flying Spur (2005–2013)

Power

552 hp

Engine

6.0-liter twin-turbo W12

Nothing says ultimate luxury power like a 6.0-liter twin-turbo W12 engine. The Bentley Continental Flying Spur is the most luxury-focused car on this list. Its engine makes 552 hp and 479 lb-ft of torque, delivered continuously and seamlessly through a smooth six-speed automatic and all-wheel-drive system.

Designed to cruise silently at 200 mph while surrounding passengers in handcrafted leather, real wood veneers, and double-paned glass, the Flying Spur offers a royal driving experience now available for the price of an average family crossover. However, this is an old Bentley.

Cadillac CTS-V (2009–2013)

Power

556 hp

Engine

6.2-liter supercharged LSA V8

Dubbed the “Corvette with four doors,” the second-generation Cadillac CTS-V built on what made the first generation great. It has a 6.2-liter supercharged LSA V8 pushing 556 hp and 551 lb-ft of torque, with brutal, instant, tire-shredding torque at any rpm.

With Magnetic Ride Control suspension and massive Brembo brakes, the CTS-V does not just go fast in a straight line; it takes corners with shocking agility. You can also have it as a coupe, and there is a wagon, but those are generally more expensive than the coupe or sedan and can take them above budget.

BMW F10 M5 (2012–2016)

Power

560 hp

Engine

4.4-liter twin-turbo V8

Replacing the screaming V10 of the E60 generation, the F10 M5 ushered BMW’s legendary super sedan into the forced-induction era. Under the hood sits a twin-turbocharged 4.4-liter V8 pushing out 560 hp and 502 lb-ft of torque directly to the rear wheels, paired with a rapid-fire seven-speed dual-clutch transmission—or a rare six-speed manual in the U.S. market.

Alongside its AMG rivals, the F10 M5 is one of the most effortless and brutal highway cruisers, with modern luxury, updated cabin technology, and a refined ride that hides supercar-level speed inside a sleek-looking 5 Series—all for under $30,000.

What to Keep in Mind

While these cheap 500-horsepower cars offer incredible value, keeping these performance vehicles running smoothly requires time and money. Here are a few essential tips before making your purchase:

• Maintenance budget: Depreciated high-performance cars come with high-performance running costs. Always budget extra funds for special fluid changes, performance tires, and high-end brakes.
• Prioritize service history: A well-documented maintenance history from a previous owner is worth more than low mileage with no records. Look for enthusiast-owned examples.
• Get a pre-purchase inspection (PPI): Before signing any checks, spend a couple hundred dollars to have a specialist inspect the vehicle thoroughly.
• Join enthusiast communities: Forums and owner groups specific to your car are invaluable resources for finding honest mechanics, preventative-maintenance advice, and aftermarket solutions.

Final Thoughts

Ultimately, these 10 cars represent an incredible golden era of automotive engineering, where big mechanical engines with superchargers, turbos, and high-revving V10s reigned supreme. For a budget of $30,000, you can have one of these serious performers sitting in your driveway.
