How to make random car from selection spawn

[MurkyMamba]

Hi All,
I am trying to make a script were I talk to someone and they send me to go after a vehicle and bring it back. How can I make It so the vehicle is random out of the ones I want?

Say I wanted a choice of T20, Adder, Tempesta and Zentorno, how can I make sure a random one of those spawn?

thanks.

Update: I got the cars to spawn via a list but they all spawn at once. Is there a way to make a random one spawn instead?
