There is a gear indicator in the a6m3 look closer. If you are talking about the half-track either this is an inside joke or you are a tool.
All I can say is wow. Just wow. lol Were you high when you wrote this? I was referring to the gear indicator on the M3 half track for the transmission.
Semp I know it's not really all that important but I do enjoy having the speedometer and gear indicator visible when I'm climbing steep hills as it helps to avoid the shift issues the auto transmission seems to have at times on them. The other GV's have had a gear indicator added back to them and see no reason why the M3 should be left out.
