Collectors have recently become more and more fond of the Classic Dodge Challenger.

In the 1970s, the Challenger was a formidable muscle vehicle.

They were made available at the time so that the Dodge could have the storied hemispherical (Hemi) engines.

Even more horsepower than the regular engines was added by these engines.

Collectors nowadays, obviously, look at Hemi-equipped vehicles a bit closer.

That is one of the reasons a certain Challenger that is now up for auction is predicted to fetch $3 million or more.
