How tall are you
6'3" with a long spine.
I've been over 6'2" since I was 12.
One of the things I really liked about 60's and 70's Mopars is that they seemed to have about an extra inch of headroom versus ford and gm.
That inch made the difference in whether I had to slouch or not.
For a couple of kickers- I discovered on my first 66 Coronet, that the seat tracks were adjustable up and down! ...and on lots of them (68-74), you can get yet an additional 1/2 inch by removing those donut spacers.
Too bad the newer cars are all made to fit a max spine length of about an inch shorter than mine...including Mopar. I can't even fit in a Challenger or Charger, let alone an Avenger. I barely fit in our P/T, and I had to take the headliner out of my 2005 Dakota at work.
