VOTE FOR THE CHARGER!
Wifey had one as a rental car that I get her when she goes 500 miles one-way to visit her Mom & family while I play zoo keeper and work. It happened to be available over a weekend when our manager double-booked us(noon charity gig in Houston for Ronald McDonald House, night gig in College Station at a ranch).....so I borrowed it. BOSE fit, 2 basses fit, my pedalboard/cable case(full size keyboard case) fit, toolbox fit. No room for anyone else after that but NO WAY in a Challenger. Now the fun parts.
Normally a full-size van is my gig-mobile at about 16 mpg and not really pushed hard(215,000+ miles so far). The Charger got amazing mpg IF you kept your foot out of it, which I mostly did. There was one pedal-masher. The ranch gig is down a FM Road(Farm-to-Market number road for those not familiar with Texas labels) that is mostly straight in light hill country. I came over a rise and saw our drummer about 1/4 mile ahead doing about 60 or so....and pedal on metal, pushed back in the seat, tach heads for the redline very fast, gears change very fast, and I pass him doing about double what he's doing before we hit the next hill. Oh, free adrenaline dump too.
Again, I'd vote for the Charger. The stereo in it kicks posterior also.
Final Note: It did make a unique sound on the first start of the morning, almost like a power steering pump needing fluid that lasted a couple of minutes but I checked all the fluids and they were OK. Maybe ask a Dodge tech/gearhead about that one.
