It's possible to get the car without a single use of lockpick skill or any items brought to the location.
Well thanks for your reply. I must be stupid or blind then. I've been clicking around on this map and checking every crevice without avail. I spawned on the south west side of the map, hence I'm on the wrong side of the map. I can't find any tunnels, items, holes in the fence or other objects I can interact with.
/edit: there is, however, a small black square in the bottom left without any textures in it.
/edit: nevermind, I was both stupid and blind
