Seriously. Just look at the prices.
The Challenger SRT Hellcat is a smash success for Dodge, with the order books filled for this year. The MSRP for one of these 707 horsepower masterpieces: $59,995. As we all know, dealerships have been taking full advantage of the Challenger Hellcat's popularity, and jacking up the prices because they can. But say you did manage to snatch a Hellcat but you're now more interested in making a profit. It's totally possible. A quick search for used Challenger Hellcats will show the cheapest one going for $80,000 with 50 miles on the odometer.
The most expensive? $129,999 with 1,525 miles. Point being is that already in a single model year this car has the potential to more than double in value. Dodge is working hard to better meet demand for 2016, but the Hellcat still won't be as abundant as lower Challenger trims. So, if you manage to buy or arrange a decent enough price for a Challenger Hellcat and feel you can part with it for profit's sake, then the answer is clear.
