The Mazda MX-5 Miata has remained the most popular sports car for decades thanks to its affordable price point, cute looks, and fun, responsive handling. The cabin is also not the best for tall drivers, with 37.4 inches of head room and 43.1 inches of leg room. Meanwhile, a person around 5'9" generally needs 39" of leg room to be comfortable. If you bring those measurements back to the same 6' 4" person attempting to sit in a Miata, they are at the very limit. While torso and leg length varies person to person, it seems like anyone above six feet tall could be pretty cramped in a stock Miata without the top down.
