I have recently met and gotten to know two auto mechanics. I think both of them are ISTP's. I knew another ISTP mechanic several years ago. I have read MBTI descriptions that connect ISTP's with this profession.
Obviously, you guys are capable of doing well in a wide variety of careers (like every other type), but using this career as an example, I'd like to hear in your words why this career (or a similar career) is appealing? What would you like about it?
