It's a tough one.
I have lots of missions that are rescue, spy, capture and other "fun" scenarios
that tests the capabilities of the FMB.
The Jeep/Kublewagen, being moddled on a P38, has serious problems damage and handling wise so limitations for ramming objects and scoring points should be investigated.
Hitting troops and horses with the jeep destroys them but theres no piont value iirc.
Sorry I cant be more help but I think your stuck with a virtual slap on the back and a gigar for the pilot who makes the rescue in the current HSFX incarnation.
PS: Being able to cross bridges with the Jeep/Kubelwagen would be a cool addition.
