Grand Theft Auto III/Vehicles

=Somethingproof Vehicles= These are vehicles that are bulletproof, fireproof, damageproof, a combination of these... and some are even everythingproof.

Bulletproof Securicar
This one's obvious, Joey even tells Claude it's a bulletproof. Just play 'Van Heist' (Joey) normally, but put it in your own garage instead of the Securicar cracking one. Then blow it up with weapons or a cheat code and let the door close. You've failed the mission, but you've got the consolation prize of a Bulletproof Securicar.

Everythingproof Stretch
The Everythingproof Stretch is only everythingproof when it's in the garage; it seems that the designers didn't want anything damaging the vehicle before it came into use, so they made it impervious to all damage until after the cutscene where it backs out of the garage. It's one of the more annoying vehicles to get, but it's more robust than a tank. Absolutely nothing in the GTA world can destroy it save flipping it over or the "blow up cars" cheat.

Begin 'Salvatore's Called A Meeting' and drive to Joey's. These methods don't always work, but keep trying.

Unfortunately due to Vice City's improved clipping you can NOT acquire the Everythingproof Stretch in this way.

Walk Though Walls method
DO NOT touch the blue corona.

Take a vehicle such as a Belly-Up Fish Van and park it on a diagonal with the wall. Then enter the "speed up time" cheat twice and run into the wedge space between the two. With luck you should be forced through the door and into the garage.

Now you have it, back up into the door. The car will go through it in a weird way and into the famous Blue Hell. After falling for a while and losing some health, the car will relocate outside the garage. Weird. Now, on to Staunton...

Kill Joey method
This may or may not work. Go in as normal and pick up the Stretch and Joey. Then continue as follows...

What To Do Next
After you've acquired the car through whichever method, use the Cars Can Fly cheat (Liberty City players: you should probably use SEAWAYS instead) and fly it over to Staunton Island. Don't worry, you can still get 100% completion.

Visit 8-Ball's bomb shop, rig it up, and then put it in the Staunton Island garage and blow it up without the door closing. Then allow the door to close and when it opens it will be repaired.

If Joey was in it, you fail the mission; if he wasn't, it is to be assumed that the game will supply you with another limo. In theory you could probably repeat this for a FLEET of Everythingproof Stretches

Some users have reported that when the Joey method is done it isn't everythingproof, so this might not work for everyone. The Blue Hell method works every time, but it's sometimes hard to get through the garage door to begin with.

Other Notes
Whatever you do, don't take it to a Pay 'n' Spray. Just like the Asukamobile in GTA Advance this is a unique colour; if you paint it, it will lose its jet-black tone and you can never restore it.

Bulletproof Barracks OL
During 'Arms Shortage' (Ray) just jump in the Barracks and drive it away. The Cartel will kill Phil, you fail the mission, but you keep the Barracks. Phil's Barracks OL is ONLY bulletproof during this one mission, so if you want it be sure to get it.

Everythingproof Bobcat
Want a near-indescructible Bobcat for your very own? This one's extremely difficult to get in GTAIII, and pathetically easy in GTA: LC. This can only be acquired during 'Evidence Dash' (Ray).

Bulletproof Patriot
WARNING: mild mission-reward spoilers follow

Definitely the easiest to get. Just complete the mission 'Marked Man' (Ray) and it is part of your reward at the end. Be sure to stow this in a garage, it will be VERY handy later in the game.

=Unique Vehicles= These are vehicles you can only acquire once, or can get earlier than in the normal game, or by glitching, or whatever.

Dead-Skunk Manana
Want to keep a Manana with a butchered body in the back forever?

This can only be acquired during the mission 'Dead Skunk In The Trunk' (Joey).

Take it to your Hideout instead of the crusher after killing both Forellis. Ensure you have full armor and health. Next, put it in the garage and get out but stay in the garage yourself. Then blow the car up, severely wounding you and failing the mission. Now leave the garage and allow it to close. When you open it next you'll have the dead skunk still in the trunk. Unlike the other unique cars, this has no somethingproof qualities; all it is is a crappy car with a body in the back, but still an interesting collectible.

In GTA LC you can spawn this vehicle at any time by typing THELASTRIDE.

Ghost Ship
In 'Gone Fishing' (Ray), Ray's partner is driving this mysterious boat. It has no textures or reflection properties so appears in a solid colour.

On the PS2 it is named the "Ghost MISSING" and appears blue, while on the PC it is merely called the "Ghost" and appears black.

Simply drive the boat near to Ray's partner and then snipe him or use an M-16 when he gets close. Unfortunately this boat cannot be stashed in a garage, but is still an interesting oddity.

Read this GTAForums thread for more about this boat.
