Porsche 718 Cayman
The newest generation of Cayman and Boxster have caused quite a stir with fans as Porsche dropped the high-revving flat-six in favor of a smaller, 4-cylinder engine. While it does sound nowhere near as good as its predecessor, the new Cayman absolutely embarrasses the old car in terms of performance. Especially in GTS guise, this entry-level Porsche is as fast in the quarter mile as a first-generation Lamborghini Gallardo. The combination of ample power, precise handling, and one of the best gearboxes in the business make the 718 Cayman a relative bargain at around 70 grand.
Chevrolet Corvette Grand Sport
While it's the Corvette ZO6 that the internet seems to really get excited about, the Grand Sport seems to be the most well sorted model in the range. The Grand Sport retains the same 460 hp V8 as the standard Corvette, while also being treated to all the suspension and handling upgrades from the Z06. This means the Corvette Grand Sport is a very capable car that can be pushed to the limit without the fear of overheating that has plagued the ZO6. At around 70 grand, it's a lot of money. For what it offers, though, the Grand Sport is the best value for buying a new Corvette today.
BMW's smallest, least powerful M-division product might also be its very best. The M2 has won many critics over with its agile handling characteristics and friendlier nature compared to the M4. It's also a good-looking car, with muscular arches and lines hinting at its performance capabilities. Add in a characterful engine and BMW interior quality and you've got yourself a very appealing package. Starting around $52,000, the M2 is a bit of a pocket rocket that'll eagerly tear down your favorite twisty road.
Ford Mustang Shelby GT350
The Shelby GT350 is as revolutionary as Mustangs come. Under the hood, it features a flat-plane crank V8 that puts out an absolutely thunderous noise in addition to 526 naturally-aspirated horsepower. However, the engine layout is not the only thing that separates this Shelby from your average Mustang. A number of chassis and suspension modifications allow the GT350 to handle more like a European sports car than its American peers. For a base price of around $55,000, that's a bit of a steal.
Mercedes-AMG C63 Coupe
While some may consider the C63 more of a German muscle car than a proper sports car, I believe the Coupe deserves a spot on this list. A twin-turbocharged V8 up front sends over 500 horsepower to the rear wheels, which provides a noise most cars can't hope to top (except for that Mustang I just talked about). Despite the C63's weight, the car handles very well, and will not hesitate to get sideways if you're a bit excited with your right foot. The C63 Coupe is not only a fast car, but also a gorgeous one filled with the latest technology that makes its 67 grand starting price well worth it.
*Disclaimer: The 2018 Nissan GT-R was left off this list as it's no longer feasible to purchase a new model for under $100,000. It's a fantastic car, but has gone up in price considerably since its debut years ago.*
