These days, it seems like there are more ways than ever to put a 500-horsepower car in the driveway. However, models like the Challenger Hellcat and Mustang GT500 carry $70,000 price tags. So when it’s time to find truly cheap speed, what options are out there? A quick look into used BMW M6 models shows that it’s possible to have 500 horsepower for less than $40,000. It’s just a matter of knowing where to look.

Twin-Turbo V8 Power

Without a doubt, the power plant sitting under the hood of the BMW M6 is a true highlight. It’s a 4.4-liter twin-turbo V8 mill, and it delivers a wallop. At 560 horsepower and 500 pound-feet of torque, the M6 fires itself from a standstill to 60 mph in around four seconds. Even better, the M6 was available with a six-speed manual transmission, so the power to row your own gears is truly in your hands.

Perhaps the most exhilarating aspect of the M6 is the way it delivers power. Not only does it accelerate like a startled cat, but peak torque occurs at just 1,500 rpm according to MotorTrend. Make easy highway passes without bothering to downshift, and the M6 will come to life and effortlessly sweep past those in the right lane.

Available body styles

The latest BMW M6 models were available in two-door coupe, two-door convertible, and four-door Gran Coupe body styles. There is much debate about which model is more fun, but we think it’s all about what speaks to you. A coupe will be the purest experience, but the Gran Coupe is a phenomenal grand tourer. The fun of a convertible is undeniable, but the M6 is already a bit of a heavyweight without the extra kit. Still, open-top cruising is the best way to hear that 4.4-liter V8 purring away, so it may be worth the trade.

BMW M6 values

The BMW M6 is a tough nut to crack in the current used car market. There are models available for as little as $27,000, while some are still going for nearly six figures. The best deals balance mileage with the purchase price, falling somewhere between $35,000 and $50,000. At the top end of that scale are M6 models with around 50,000 miles on the clock. Meanwhile, cheaper examples can have up to 80,000 mile markers behind them.

Is the BMW M6 reliable?

While the 4.4-liter twin-turbo V8 is surprisingly reliable given the power, the transmission in the M6 can be problematic. Issues including fluid leaks, a blocked transmission fluid filter, and transmission sensors are common with these BMW grand touring cars. Other issues include a host of BMW’s best hits: water pumps, gasket leaks, and coolant hoses. Consider those wear items on any BMW and have them replaced every 75,000 miles to avoid potential headaches.

GT comfort and supercar performance for less than $50,000

The BMW M6 is certainly an affordable choice, offering impressive performance and immense comfort, even in older models. Just keep some budget handy to perform the maintenance: Oil changes in this massive engine can cost up to $250.
