There's no way you can write anything off on a purchase? If you can obtain a loan (maybe with a co-signer) you're payments will be not too far off from those astronomical lease payments... And you OWN it! One other word of advice (might not be good) is that if you are going to rely on this car to get you around for work and is your only means of transportation, it may get REALLY scary in the snow! Especially in NY traffic and driving maniacs
I had a 300ZX back in the day as my daily driver and it was very scary driving even in 1/2 inch of snow! You gotta think about practicality and what is going to get you to work...After all, that is how you make your chedda! Sorry if I sound like a downer but I'm just speaking from experience. Good luck in figuring this all out!
