A lot I picked up from my dad, more maintenance items than mod items but learned my way around a car. The mods really came in oddly enough on my first car my '95 Chevy Monte Carlo Z34. Started out small with exhaust and some things there. Then everything branched off of that when I got my now DD, 2006 Pontiac G6 GT. Just picked things up online... Now slowly moving into it on the Camaro
