Setting owner to spawned vehicle

I have a script that spawns a jeep but i am having trouble setting the jeeps owner to the player who spawned it.

function vehiclespawn( ply, com)
local Jeep = ents.Create(“prop_vehicle_jeep_old”)
Jeep:SetModel(“models/buggy.mdl”)
Jeep:SetKeyValue(“vehiclescript”, “scripts/vehicles/jeep_test.txt”)
Jeep:SetPos(ply:GetPos() + ply:GetAngles():Forward() * 250)
Jeep:Spawn()
Jeep:Activate()
end
concommand.Add(“spawnjeep”, vehiclespawn)

I would greatly appreciate any help you can give.
Thanks

[lua]
Jeep:SetNWString(“Owner”,ply:Name())
[/lua]
Assuming you use SPP

Do you know any different way of spawning a jeep because I am having problems with this way?

It’s not jeep_test.txt or prop_vehicle_jeep_old. Those are both depreciated.
