The 155 arty is cost inefficient for what it does and the mark target is only an accuracy buff + loiter.
The commander ability now provides the WC51 (crew, cap, drive-by, HMG ), the M3 (reinforce, heal), mark target and off map barrage. It simply too much.
Both of them have very little use early game but allow the unit to offer a supporting role late game.
The kubel should be given something more, rather than stripping away from the Jeep. The new axis halftrack is similar - it gets to be a reinorce point, bunker down, move mortars in the late game to stay relevent.
Of course the Kubel compares poorly, but the average kubel survives ten seconds and desperately needs some late game utility if it ever wants to see the light of day late game.
CoH2 is all about squad preservation. Units that sharply depreciate in value aren't condusive to that. The Jeep is - early game, but needs MU to upgrade (no gun until a few minutes in) and retains some usefullness late game rather than being a worthless popcap sink.
Unsure why it's 0 fuel, though. Surely it should be 5 or 10.
The WC51 combined with car riflemen can easily wipe units even without the HMG.
It can also be used to kill steal any hmg not is garrison or being baby-sited by grenadier forcing even more defensive play from the opponent.
Once more in its current state the unit is simply OP.
