Just to extend the debate on the subject of 15 and firsts (First J class mission with extended stay LM and as you say the first manned car) there’s also a debate about whether the Command Module Pilot, Al Worden, holds the record for being the individual has been closest to the Moon without landing on it…
The mission flew a different profile from many earlier flights with the LM\CSM combination for some time being in an orbit that put the combined vehicle well down below ten miles of the mean surface level at one point, seemingly almost skimming the peaks of the Appenine mountain range, and probably closer to the surface than the Apollo 10 LM crew got.
