Depends on how you define first car.
1)
1990 300ZX Twin Turbo
Dad bought it as a toy, and being that I really only drove to school and back (my HS was only 2 miles away) it wasn't really a big deal for it to be "my car". I later bought it off him, or well, paid for his boat in exchange for full time custody of the Z
2)
1995 240SX SE
Parents picked it up for $3,500 in September of 03 for me for college. So again, technically it was my car but I didn't pay for it. My mother is driving it a lot now (and having a blast in her own words) but it's still mine long term (hope to strip and build for autoX).
3)
2005 Legacy GT
First car that is outright mine.
