The LSPD are considering replace their old outdated 2005 Savana's with newer 2016 Express's. The Express model they are considering is the 3500 extended chaises and will be lager then the current Savana's . The lager newer van will be able to carry more officers on Raid and other high stakes tasks, and can carry more prisoners when doing transport to the prison.
I DO NOT mean any offence to GlitchGamer with his Savana model, I'm just noting facts about the real life specs
Currently I have no Transport Van release planed
