by In Minnesota, USA, a whole collection of rare Pontiac muscle cars has been discovered. A total of nine cars stood abandoned for 20 years until they were found by accident. 
Apparently, a fan of the 1974 Pontiac Firebird collected the cars, as eight out of nine are exactly such coupes. Moreover, four cars are equipped with the top 7.5-liter V8 Super Duty-455 (SD-455) engine with a power of 290 hp. 
In 1974, only one thousand Pontiac Firebird SD-455 were produced, and it was the most powerful American car of that era.
It accelerated to 100 km/h in 7.3 seconds and reached about 220 km/h. It should be noted that during the 1974 fuel crisis, few models in the US didn’t lose power, and the Firebird was one of the last classic muscle cars. 
One of the Firebird SD-455 has only 56,000 km on the odometer. Additionally, there are 5.7-liter coupes and one car tuned for drag racing, traveling 402 meters in 9 seconds. Finally, the collection includes a 1972 Pontiac LeMans.
Now all the Pontiacs will be sold at a Barn Finds auction. Surprisingly, the rare muscle cars are not expensive: the starting price for the cars is from 3,500 to 6,000 dollars. And this is not for rusty wrecks, but for cars in decent condition!
