I am 6'-2" and 205 lbs. My head has an inch or two of clearance under the soft top. And the seat has much more rearward travel than I can use. A friend has an old Miata, and it is a much smaller car, both outside and inside.

... I can't drive without bending my right leg so much that it is not supported by the seat... and the seat raised...

The seat tilt mod raises the front edge of the seat so that it supports the leg.

Have not adjusted my seat up or down since I got the car. Didn't know it could be raised or lowered.
