Nah, I don't think you'll have any problems. I'm 6'1" and I have my seat as far back as possible and the steering wheel up about 3/4 of the way. There's plenty of room. The seat is very adjustable, along with the steering wheel. You'll be able to find a comfortable and safe combination. :thumbsup:
Looks like you should be OK. In case you don't know this, just be aware that the pedals aren't adjustable, unlike on the LX cars (Charger and 300). But because of its shorter wheelbase the Challenger's interior is not as cavernous as its sister cars' and the pedals are pretty close to the driver (I actually wish they would go back a little myself and I'm only 5'9").
Thanks for the responses everyone. I know I'll obviously be testing one out first, but it'll be a few months yet and I'm impatient with the questions lol. Also there's not really much around here for car dealershipso I'll probably have to drive a ways to find the right one
Just wanted also add that reaching won't be a problem. I'm 5' 6" too, and I find this to be one of the most comfortable (and adjustable) driver seats I've sat in, and I've owned/driven 10 vehicles before my Challenger, from a Hyundai Accent to a Ford E350...
