Here's 21 of our favourite vehicle mods, including real supercars, bikes and military aircraft, handling variations, cosmetic changes, oddities and some plain old cool-as-fuck motors. While Rockstar is quick to chop down any mods that might hamper the GTA Online experience, there's a thriving community of creators turning out creative, realistic, funny and damn useful mods for the PC player. There's one thing the PC version of Grand Theft Auto 5 can do that the console version of the game can only dream of: mod support.
