What is the least appropriate car to arrive at a funeral in?

Showing up at a funeral in a Twingo I is like bringing a sociopath.
You might be sad to see your mother's coffin disappear behind the curtains, but everyone will remember how the one you brought with you was smiling without a care in the world as you left.

>show up in Food Mustard
>do a burnout as you leave
>come back later to collect your payment from the morticians

Context: this car says "yes I am from Yakuza and I killed your beloved relative. I'm here to laugh at you"

How so? It's pretty solemn. It's not like it's Lady Di's funeral.
Not sure anyone would pay attention to that.

>show up in Mustang
>try to do burnout
>mount curb and die instantly
>double funeral scheduled
