Porsche 550 Spyder
The Porsche 550 was a racing sports car produced by Porsche from 1953-1956. The first three hand built prototypes came in a coupé with a removable hardtop. The first raced as a roadster at the Nurburgring Eifel Race in May 1953 winning its first race.
Perhaps the most famous of the first 90 Porsche 550's built was James Dean's "Little Bastard", numbered 130 (VIN 550-0055), which Dean fatally crashed on September 30, 1955.
The 550 Spyder enjoyed a storied career, with 90 examples being built. Of those 90 cars, 43 of them were built as non-race, “customer cars".

The 550 Spyder was powered by a flat-4 producing 110hp sent through a four-speed manual transmission.
The Porsche team raced the 550 with outstanding success.
In 2012 a 1955 Porsche 550/1500 RS Spyder sold for $3.685 million at Amelia Island setting a new record price. Advertised as "one of the most genuine 550s in existence" at least two bidders agreed. Pre-auction estimate for the 550 Spyder was $2.2-$2.6 million.
The 550 is among the most frequently reproduced classic automobiles.

1966 Porsche 906 Carrera 6
The Porsche 906 or Carrera 6 was the last street-legal racing car from Porsche. It was announced in January 1966 and 50 examples were subsequently produced, meeting the homologation requirements of the FIA's new Group 4 Sports Car category.

The 1966 Porsche 906 was powered by a 1991cc flat 6. The engine regularly fitted was the 901/20 lightweight racing engine with 220 hp and carburetors.
Some examples that were raced by the factory team received fuel-injected or 8-cylinder engines.
At the 1966 24 Hours of Le Mans, the 906 placed 4-5-6-7 behind three Ford GT40 Mk IIs, outlasting all of the previously dominant V12-engined Ferrari Ps
A 1966 Porsche 906 Carrera 6 appeared for auction last year in Scottsdale with an estimated value of between $2 million and $2.4
Porsche Carrera GT
The Porsche Carrera GT is a mid-engined sports car that was manufactured by Porsche between 2004–2007 in Leipzig, Germany. Sports Car International named the Carrera GT number one on its list of Top Sports Cars of the 2000s, and number eight on Top Sports Cars of All Time list.
The Carrera GT is powered by a 5.7 litre V10 engine producing 612hp. Porsche claimed the car would accelerate from 0 to 60 mph (97 km/h) in 3.5 seconds with a maximum speed of 330 km/h (205 mph). By the end of production on May 6, 2006, 1,270 GTs had been sold, 644 units sold in the US and 31 units sold in Canada. In the UK, 49 units were sold.

Technology includes a pure carbon fiber monocoque and subframe, dry sump lubrication and inboard suspension. At speeds above seventy mph, the Carrera GT raises its rear wing into the airstream to reduce lift. Both its front and rear suspensions comprise pushrod actuated shock absorbers and dampers with anti-roll bars.

Original base MSRP was around $442900 in 2005. Today that could be about double.
2018 Porsche 911 GT2 RS
The GT2 RS becomes the most powerful Porsche ever released — the 3.8-litre flat-six and its two turbochargers pump out 700 horsepower and 553 lb.-ft. of torque anywhere between 2,500 and 4,500 rpm.

Power is relayed to the rear wheels through a seven-speed twin-clutch transmission and the widest tires ever installed on a Porsche. The front tires measure a substantial P265/30R20. At the back, they blossom to a full P325/30R21.
In stock form the 911 GT2 RS has a power to weight ratio of just 2.1–kilograms for horsepower. This means a top speed of 340 km/h and a run from rest to 100 km/h of 2.8 seconds. It hits 200 km/h in 8.3 seconds.

Base price is $ 294,000.
997 Porsche Turbo might be the ticket
If you are looking for an extremely fast, fun to drive sports car with all-wheel drive and more power than ever needed, a 997 Turbo might be the ticket. The Porsche 911 was manufactured and sold by Porsche between 2004 (as Model Year 2005) and 2012. In 2012 it was replaced by the new 991.
Now a decade old, the car is not that slower than modern supercars costing ten times as much. The car is capable of a sub 4 second 0-60 time, and boasts a good record of reliability and longevity. The "Mezger" engines in the 2009 and earlier 997 Turbo produced about 480 horsepower and aside from coolant leak issues it has been a faultless engine.
The 997 Porsche 911 Turbo gets a lot of attention as the bargain Porsche to buy.
Older, air-cooled 911s have skyrocketed in price to the point that they're no longer affordable. The 997 is still unloved among many Porsche fans, and you might pick up a 997 Turbo for something like $50,000.
