I wouldn't buy a sports car living in New York , the driving season is to short you only have 5-6 months to drive the car before it needs to be stored.
It makes more sense to update your daily driver for between $5k-$10k save you hard earned money you saved, pissing it up on a $30k season vehicle isn't worth it, unless you can afford to throw away money.
