3500 in the bank.
Dont spend it on the 1990 Integra.
That's my advice.
Save up for a hatchback or a newer Teg.
JMHO.
If you are determined to spend the money on the car, decide what is more important to you.
1) Looks
2) Performance (all aspects)
3) A combination of the two.
Then decide if you want to put all of that to say, a turbo.
or some suspension work and some side molding painting and wheels/tires/brakes
I'd suggest saving up another 4k and finding yourself a nifty GSR or just go buy an older hatch with that money and save up for a swap later on.
