My brother works for UN, based out of NYC. He lived there for about 2 years with a similar rent $/mo. He never drove anywhere though? He didn't even bring his car with him; I think adding a couple cars to the mix will be costly there?
I'd suggest doing the 2 hour comute and get your bearings; something good will come up? If it doesn't, I'm sure you could get a variance on the 90 day policy based on you completing your homework?
Good Luck, my wife and I really enjoyed our time in NYC!
Cheers,
Made it to the NY car show while we were there too:
