Depends on which engine you're referring to, as there were several engine options for the Challenger in 1970.
Cannot be answered at present since we're still in the 2010 model year.
pull inside door panel off and look inside the door and unhook the glass from the regulator and pull the glass up out of the door, to reinstall drop new glass into door channels and hook to regulator by factory hook-ups.
The car goes at 230mph. A very impressive car afterall. pss.... the konzegg goes at 250mph faster than the Bugatti veryon supersport.:)
Assuming you're referring to the 5.7L Hemi, yes
It will vary by location and by what engine you get. I traded a Chrysler Sebring coupe in on a 2010 V6 Challenger and my insurance only went up $20 per year. But a big V8 will up your insurance more.
The 2012 Dodge Challenger is a gas-powered vehicle.
