I've just found another one! The first two clips, with the exploding green Caprice, and the police car being landed on and exploding, are from the 2002 made-for-TV movie DEAD IN A HEARTBEAT.

I figured the footage looked like a low-budget made-for-TV Die Hard rip-off, so I went to the Die Hard Scenario wiki - because of course that exists - and checked through some lists, notably the "Die Hard in a hospital" list. "Dead in a Heartbeat" was the first one I checked out, and bullseye. I seriously love when that happens.

I just have the exploding Volvo and the black car going off the cliff left to find.

Looks like we only have Season 1 completed. Amazon Prime seems to have both season available to members.

Okay, so, I've just solved half of these (movie-wise), purely incidentally, and of course, right after I asked for help. That happens every time.

Turns out the Crown Vic jump, Intrepid/Impala collision, smushed Corolla wagon, and flipped Econoline, were all from season 2 episodes of the Steven Seagal TV show TRUE JUSTICE.

If you wanted more fuel for your Seagal hatred, think of that poor Corolla... that'll do it.

And yes, I confirm that the Crown Vic didn't just turn into an Intrepid. What happened was, the Crown Vic and the Intrepid were doing a game of chicken. The latter lost and crashed into the Impala.

Ah, now I see Caprice when viewing.

For the last one, not an Alfa or a Fiat or derived. I thought about the Jetta A2 too, but perhaps something looks off? Or maybe is a Toyota or a Nissan?

I'm pretty sure the jump and the crash are two separate clips that have no direct relation (aside from clearly being in the same movie).

But thanks for everyone's help, I really appreciate it.

The black car at the end is really the toughest one. I thought it was another Volvo at first, before realizing Volvos don't look that ugly. Well, when compared to a Volvo.

i'd agree on Tracer but the green one , the way the mirrors are and the dashboard , i'd go for 1994 Caprice

This is what I see:

0-0:06 - green car looks like a Ford Taurus, red hatch looks like a Mercury Tracer
0:06-0:21 - 1991-1992 Chevy Caprice
0:22-0:26 - 1998+ Ford Crown Vic
0:27- - 1993 Dodge Intrepid smashing into a 2000 Chevy Impala
0:33-0:44 - 1997+ Ford Econoline
0:45-0:50 - Volvo 740

For the last one I was thinking something like an Alfa Romeo of the late 70s/ 80s but it does not match. Or some Fiat or license from that? (Tofaş)

0:26 collision : car being hit is a 2000-2005 Chevy Impala
ca that hits it : well.. 1998+ Ford Crown Vic in the air that magically turns into a 1993-1997 Dodge/Chrysler Intrepid when it crashes into the Impala

0:28 wagon : 1988-1990 Toyota Corolla Wagon ( i just can't believe they scrapped a rare bird like that just for that.. )

0:51 still gives me trouble.. 1985-1992 VW Jetta ?

Hope it helps
