Ive been pondering the same thing, although im buying a used Viper, where payments are extremley manageable.
At 4.49 from People's First Bank, with 5,000$ down on a 35k car, the payments last time I checked (2 weeks ago) was around the range of 440.00$
Im a kid (15) , I make 1200$ amonth on all forms of my personal income...and I MUST have a classy car thats fun to drive...I don't like shiitcars.
I bought my DeLorean as a investment/toy and [******] happened...so don't buy a car thinking of it as a investment, otherwise you'll never fully appreciate the car...its a tool of enjoyment....enjoy it.
Unless your going to buy new (2003 SRT-10 NEW!) then why pay full price? Buy a slightly used car in excellent condition and pocket some of the money for the car or other things, it pays to have fallback money just in case.
Don't take it as advice because of my age (inexperience) , its just my opinion.
