The problem with wheel locks is this

Most wheel thieves carry one with them, your locks will only slow them down a few minutes, I have seen one guy on you tube that put a tow chain and lock thru all 4 mag wheels every night.
I hate to say it but living where you do , your really better getting something that they will leave alone and something you really don't have to worry about getting stolen or damaged while being parked or simply driving in NYC traffic.
On a trip to NYC in my beat up old nissan frontier pickup , I can remember being hit or pushed to the side by a lot taxi cabs in the city, at least 5 times in 3 days, so I can't imagine driving something nice and brand new in that city, in a short tme any decent car will turn to a POS there. Just look at whats parked on the street, slowly your car will turn into one of these.
Your really better off with something like a stripped down automatic versa or a used sentra etc, for NYC.
The other factor is that this will definitly effect your insurance, watch them drop you during the 6 month period, unless you move the car or get something else, right now you are a hi risk for them.
