Cleaned dark mold in car w/ bleach mix and sponge. Small area (4-6 inch). Caused by coffee. Used gloves but no mask. Should I worry about exposure?

I wouldn't worry:) Using gloves ... good for you! If you did not experience any symptoms such as coughing or shortness of breath, I wouldn't worry about the bleach fumes. High concentrations of bleach can cause lung irritation/inflammation which typically heals by itself. If you didn't have symptoms, not a problem. A mask is a good idea, though:)
