For what it’s worth, I’m 6’4” and weigh anbout 215 and the 550 was just out of the question. There just isn’t any room to move the seat back. That’s when I went on a 356a replica hunt. This will be my second year with a 356 and what a great choice. I easily fit in the car and I believe you would too. I have to scoot the seat up 4-5 clicks. My inseam is 34” and you would probably fit without any seat modifications. And even if you needed to modify I think they would be relatively easy. I say you need to start looking at the speedsters. Much more room, and just as zippy with the right engine.
