Anyway, vehicles are unique in a way that they can have special color, have some sort of proofing on it or is an entirely different model. Below are the terms used to describe a vehicle and their explanation.
(Yes, I know the headers below suck but there are no tutorials to make LCS-style text. I blame internet.)
|BP||Bullet-Proof||The vehicle cannot be damaged by gunfire. You can empty out your entire Minigun ammo, it won't make a difference.|
|DP||Damage-Proof||The vehicle does not take any visible damage. Crashing all you want will not damage the car at all.|
|EP||Explosion-Proof||The vehicle cannot be damaged by explosions. Shoot an RPG at EP car. It'll do nothing.|
|FP||Fireproof||The vehicle cannot be damaged by fire. Flamethrowers and Molotovs are useless. That means getting vehicles with Flamethrower Trick won't do anything.|
|CP or AP||Comprehensiveproof or All-Proof||The vehicle cannot be damaged by anything. Note: This term was usually referred to BP/DP/EP/FP properties only and it's still like that, don't get confused!|
|H||Heavy||The vehicle is heavier than normal, making it able to push all cars out the way. This also comes at an disadvantage - the vehicle is way easier to destroy if it has heavy property. It's recommended to DP the car if you want to have fun with it.|
|UH or SH||Unique Handling or Strange Handling||The vehicle has a different handling than normal, making it easier to turn or accelerate. This is most common on bikes, in fact, I haven't actually seen a car with UH yet.|
|WP||Waterproof||The vehicle dives through the water into blue hell. It's also possible that Heavy property does that so it's possible that this property idoes not exist. Has anyone tried diving a H car?|
|EC or UC||Exclusive Color or, simply, Unique Color||The vehicle has an unique color not seen in normal traffic or at Pay 'n Spray.|
|PC||Permanent Color||The vehicle will never change color without hacks. You can spend all your money in Pay 'n Spray (resprays are free lol), but it will not change anything.|
|TP||Tip-Proof||The vehicle will not go on fire when upside-down. Note: TP cars CAN go on fire when upside-down so quickly exit the car before it goes on fire.|
|PP||Pop-Proof||The vehicle's tires cannot be shot or popped by spike strips. Shooting them with Sniper Rifle will not pop them.|
|DD||Double Damage||The vehicle can take twice more damage. It can mostly be seen during on-rail shooting sequences that include a Maverick you have to destroy. They usually take a while to destroy even with an M4 that destroys the vehicle very quickly.|
From cheatless tricks for clean players to full on Cheat Device exploits for Dons of All Liars. List here.
Not all missions have unique vehicles but still there are quite a few. Crossed-out missions mark ones that do not have any unique vehicles. Links will be posted as soon as a post is made.
