Not sure about $500. have you asked your dealer how much the delivery charges would be? I know someoen else was also looking to deliver to concord and were quoted $1500. BMW of concord told them they would rather sell tehm a M3 for $1500 over so that tehy wouldnt ahve to worry about Delivery charges.
I will ask my SA how much it would cost approx from new mexico. Think he would rather sell you one of there allocations though for the delivery charge price.
What status are you at in New Mexico?
