Look what I found!

I think it is open to the public. The road is a few hundred feet away

Meh- if it's in a public area and abandoned, I probably wouldn't have any issues with removing the 'junk'.
Do you plan on dragging the entire car out/ or do you want to disassemble it and cart it off?? You can just break it down into manageable sized pieced and drag it to the side of the road and make a pile (away from traffic) and come by with a truck and scoop it up.
Hood/trunk lid/doors/bumpers? catalytic converter? battery? starter? alternator?
