A number of the 90" wheel base cars can fit a close to 6' guy without a problem, some not so easy. Being able to move the SEAT back far enough is generally the key. Some cars don't have an adjustable seat. You COULD reposition the seat (drill new holes, remount) but I prefer an adjustable one. You'll be fine in a 90" wheel base in general. I'm right at 6' and do NOT have my seat all the way back! However, I like to wear the right SHOES when I drive it! Large shoes or boots (and flip flops, I'm in Hawaii after all) are all out of the question! I find a modest pair of tennis shoes works best.
I drove a slab side Aurora replica (no longer made, was from Canada) and was surprised how 'tiny' it was compared to my ERA! I assume it was made close to original specs (length\width), man those slab sides WERE small!
