As you already have this film listed I thought I would send these (rather small) images....

BTW I could see no Volvo in the copy of the film I have.

SEDAN - Oldsmobile?


SEDAN - Station Wagon - Unknown


SEDAN - Unknown

Thanks.

The Volvo is maybe briefly visible in the background in one of the scenes?

I will look at it again sometime to confirm (there is possibly a night-time scene I may have missed). However there are very few scenes that have any opportunity for action involving vehicles and I think I covered them.

It may be an error in the list, that already happened for movies that had similar titles.
