Well,i love unique paint jobs. I had the BP/FP/PP/EC Stretch at some point,but i ditched it in favour of the EC Comet. You can get a BP/PP Limo from Sunshine autos anyway.
Little offtopic: Started playing GTA 3 today. I will complete it 100% as well. I will try to collect some special vehicles ,that's for sure.
I got 100% in GTA III. 0 Cheats, 0 Deaths, 0 Times Busted, 4 Missions Failed, and 7 proof vehicles. I had to fail 4 missions to obtain the BP/FP Trashmaster, AP/EC Stretch, BP/FP Securicar, and BP/FP/EP Cheetah. I have those 4 vehicles, plus the BP Patriot, BP Barracks OL, and BP/FP/EP Bobcat.
However, after using the legendary Crusher Glitch, these are the final 7 vehicles I have in GTA III:
BP/FP Securicar, AP/EC Stretch, BP/FP Trashmaster, BP/DP Barracks OL, AP Bobcat, BP/DP Patriot, AP Cheetah
The Crusher Glitch can convert almost every vehicle in the game into DP form. I converted the Barracks OL, Bobcat, Patriot, and Cheetah. It will NOT work on the Trashmaster and Securicar, unfortunately. Also, that BP/DP Barracks OL is a LARGE vehicle, which means it's "heavy" like a Fire Truck, but not an actual HEAVY vehicle in LCS/VCS, but it still pushes ANYTHING out of it's way and is VERY FUN to bash vehicles.
Good luck, if you need any help, you can always PM me. This is what I got in all 5 3D Era GTA Games, actually:
