@Douglas, which 10 did you get?
The Crusher doesn't make the BP/FP Securicar DP and it does not make the BP/FP Trashmaster DP. The only way to get the Securicar to SSV early is by pushing it through the ground near the Portland safehouse. As for the Trashmaster, I stored this vehicle "in memory" while completing the last 4 Portland story missions, thus allowing me to just drive it over the Callahan Bridge and to the SI Garage.
The Crusher works on the BP Barracks OL, BP Patriot, BP/FP/EP Cheetah, and BP/FP/EP Bobcat...
I only have 7 vehicles in GTA III, but there is only a total of 8 original proofed vehicles in the game. I got the BP/FP Securicar, AP/EC Stretch, BP/FP Trashmaster, BP/DP Barracks OL, AP Bobcat, BP/DP Patriot, and AP Cheetah. The proof vehicle I didn't get is the EP Securicar, but I didn't want it since I got a BP/FP Securicar.
