Like...a year?
I know my dad got his '89 Mustang (which he still has) two months before he met my mom, and he got his Mustang in '94. They got married in May 1995. I was born almost exactly 400 days later. I think my dad was 19 and mom was 20 when they were married, so I'm like the only existing near-adult who has parents who aren't 40 yet and have a little sister who is <4 months old.
