2005–06 Ford GT: +48%

Despite a production run of 4,000, the GT is a hot commodity according to Hagerty. The car has tacked on sizable gains. In the last six years it is a 48% rise in value. Today, a #2 (excellent) example will cost about $590K. For the money one gets a supercharged 5.4-liter V8 pushing 550 hp and 500 lb-ft of torque. The car hits 60 mph in roughly 3.5 seconds. Paired with a Ricardo 6-speed manual, it is now among the most collectible analog supercars.

Bad Porsches

The worst words for die hard Porsche fans is 'entry level'. First among these is the 914. Porsche decided to collaborate with Volkswagen and create the mid-engine 914 for the 1970 model year. The 914 was a mix of Porsche engineering with VW pieces that included the air-cooled, flat-four with all of 100hp. It sold well and over time its charms have become more apparent.

The 914’s replacement, the water-cooled, front-engine 924 was also built from VW and Audi parts. It debuted in 1976 and absolutely no one was overwhelmed. Its Audi-sourced 2.0-liter four now made a pitiful 95hp in North America.

The worst Porsche of all time? Some say it’s the Carrera GT, Porsche’s 605-horsepower effort to stake out supercar territory. Built around a 5.7-liter V-10 from the failed development of a Formula One engine, nothing about the mid-engine Carrera GT is Porsche at its best. It’s the Carrera GT’s nasty handling, lack of stability control, and grabby clutch that make it dangerous.

The Carrera GT will always be infamous as the car in which Paul Walker was riding when he was killed in 2013.

1959 Cadillac Eldorado Biarritz = $324k

In the late 1950s, Cadillac was the undisputed heavyweight champ in the full-sized luxury car market in North America. Cadillac used the nameplates "Eldorado Seville" and "Eldorado Biarritz" to distinguish between the hardtop and convertible. The 1959 models came near the end of the 3rd generation. The 1959 Cadillac is remembered for the largest tailfins ever and dual bullet tail lights.

While the 1959 Eldorado was misunderstood in its day, collectors today recognize the car's combination of power, presence, and unbridled extravagance.

The Eldorado featured the ultimate engine of the late 50s, the Q-code 390-cu.in. V-8, topped by three two-barrel Rochester carburetors producing 345 hp.

This concours quality example made $324k in late 2018.

1970 Oldsmobile 442 W-30 - $28,600 in 2020

1970 Oldsmobile 442 W-30 presented as Lot S152 at Mecum Indianapolis. Oldsmobile’s premiere muscle car of the 1960s, the 442 was a choice upscale muscle car. The 442 started out as a performance package for the 1964 F85 and Cutlass. Starting in 1964, “442” stood for a 4-speed manual, a 4-bbl carburetor, and dual exhausts – all of which were standard.

By 1970 the 442 had Oldsmobile’s big-block 455 V8 which was rated at 365 horsepower and 500 lb-ft of torque. The W-30’s advertised horsepower figure was underrated and was over 400hp. The W-30 package included a performance tuned Rochester Quadrajet 4-barrel carburetor, a high performance cam, and a lightweight free-flow aluminum intake manifold. A set of high-performance cylinder heads and exhaust manifolds completed the picture. The W-30 had enough juice to frighten most drivers when the pedal hit the floor.

The 1970 Oldsmobile 442 W-30 is widely considered the best Oldsmobile muscle car ever built. It is also likely the most underappreciated and affordable today.
