If you are going for a WWII homefront Casualty Notification scene, that wasn't how it worked. The in-person notification didn't come about until late in the Vietnam War. In WWII, the family received a telegram of notification. I have the actual telegram delivered to my wife's great grandparents notifying them when their son (my wife's grandfather) was shot down and missing (presumed dead) over Belgium in WWII. I also have the subsequent telegram notifying of capture as a POW and being still alive.
Additionally, the clergy would be an Army Chaplain and in uniform as well. The notification team consists of a Casualty Notification Officer (CNO, CPT or higher) and a Chaplain (also a CPT or higher). There is no driver, the Chaplain drives while the CNO prepares himself to deliver the bad news.
I don't know of any figures that would fit your scene exactly. Best bet is to find some officer figures in dress uniforms and modify them. Maybe some of Tamiya's Famous Generals set or a resin officer figure.
If you just want a Chaplain-type figure, Warriors makes a Chaplain and GI figure set.
