Keep it stock, or make it your own?

Back when I was in high school all my friends had cool muscle cars. I worked a full time job and went to school to buy a car and she was BAD. it was a 1987 formula firebird, T top, 5 speed in dark blue. It came from a one owner, garaged its entire life, old lady.

I was so proud of that car. I payed for it my self in cash and still could make my monthly rent on my shity apartment in Hayward. (I left home at 16) when I have kids they will buy there own cars way before they drive any of mine.
