Just my opinion, but the crown vic is a bit too heavy unless it was stripped for parts and set on fire. The bullet holes are a nice touch, but unless someone has really good aim, add some more in the body, not just in the glass.
I like.
Ditto on the bullet holes, but otherwise I think the Vic looks just like an abandoned and abused car corpse, never to run again.
The truck looks really messed up, but may still show a heartbeat.
Both would make excellent pieces in a waterfront scene involving police, cranes, reporters and big puddles around each vehicle - but you would need to Glosscote them - it's wet at the river bottom.
