What you are trying to do is not going to work, make your table this format:
vehicles =
{
[ 1 ] =
{
[1]={ 2902.6318359375, -2043.0684814453, 3.208420753479, 0, 0, 270 },
[2]={ 2902.5588378906, -2046.3167724609, 3.208420753479, 0, 0, 270 },
[3]={ 2902.4799804688, -2049.8156738281, 3.208420753479, 0, 0, 270 },
[4]={ 2902.4121093755, -2052.8154296875, 3.208420753479, 0, 0, 270 },
[5]={ 2902.3391113281, -2056.0654296875, 3.208420753479, 0, 0, 270 }
}
}
Then change this:
VarX = ("Vehicles"..vMap)
Into:
VarX = vehicles [ vMap ]
