Just a bit of additional info - Phyl
In 1971 I had the Dodge Charger. BTW 420 hemi engine, black, sold it to my brother at about 120,000 miles 6 years later. He had it over 250,000 miles.
My 2009 is a black Dodge Challenger - twin of the Charger. They switched styling. Charger is the 4 door; Challenger now the two door. And, 1971 beats out the horsepower. Was 420 in Charger, now 380 in Challenger. Nowhere near the 800+ in the Hellcat.
One final point - I started driving in 1963 (?); to date I've had one speeding ticket (2012?). It is carefully watched, too, by people and PD. Our leader John also had a 1972 Charger. But, he admitted to a heavy foot.

Love my hot rod.
