<blockquote I daily drove this '97 S14 for about 7 years and 100k miles. If you are 6'3" you may be challanged to fit. At 6'1" I was tight with my short hair brushing the headliner.
You must have a long upper body.
My dad, at 6'4", fit fine in the S14, but not the S13.
I'm 6'1", and I not only fit great in the S14, I fit in with a helmet.
It's better to get one without the sunroof though - it takes some space away.
My dad ordered a rare car - an Le without a sunroof option, which they all usually come with.
