Debating on A Body or B Body for first car

How tall are you now and how tall do you think you're gonna get? That would have a bearing on my decision. I'm pretty tall (tween 6-2 and 6-3) and although I fit in my 64 Valiant, I did move the seat back 1.5". Big people kinda "wear" an A body. Just something to think on.
Yea im a big guy too and my legs kinda squeeze under the steering wheel getting in and out. But the bench seat is nice and comfortable when I get situated lol.
