I'm a big fan of this compact seen here in the trailer. (1:47-1:49)

Given the setting of the movie, I'm sort of 95% certain it's a Mazda 121 DA but I can't tell if it's a mazda 121 or a kia pride. Also similar to our imported ford festiva from the late 80's and early 90's.

I can't find any clips with this car getting hit from behind and spun around. After it gets hit in this shot there's a shot from the front with a good view of the front in the actual movie.

just trying to contribute. this is an awesome site! thanks

Could it be a Daihatsu Domino (cuore)?

wow pucamor. I think you got it right. stinks for me. but the placement of the low fog light on the left of the bmper, the big area for the license plate, the clear placement for the reverse lights, etc etc. It's a good match!
