Production of the Demon 340 began just one year prior, in 1970. At that time, Demons were sold for around $2,000—which is the modern-day equivalent of roughly $15,000 today. In the following year of its production (that is, 1972) even fewer Demons were produced, and sales dropped along with the production.
Today, the Demon 340 boasts a small but loyal cult following. You can come across 1971 Dodge Dart Demons at car shows and auctions, and, according to Classic’s statistics, the average cost of a second-hand Dodge Dart Demon 340 today is between $30,000 and $50,000.
