Never drove a 535. Test drove a 550, felt too big for my liking.
F30 335i is a remarkable vehicle. Best I've ever owned. I love it. I've already put 2200 on in my first month of ownership. I take it out whenever I need to clear my head or just relax. I still get all warm and fuzzy every time I get out of my car after a healthy aggressive road session.
Go test drive one and see. Size wise is fine for me, but I'm only 5'11. My friend is 6'3, he had no major issues when I let him drive my car. Only concern might be the sport seats. Those side wings aren't forgiving if you are of a large stature.
