The most influential car of my childhood is probably that of my uncles 930 Turbo, or his E30 M3. The first car ever driven by me, on my own, was my dads 1971 Corvette LT1 at age 11-12. I learned to drive stick in it, and do massive burnouts.
current car: mk4 .:R32
my first car bought, was at age 15 1/2. A 85 pontiac fiero gt with a ppg metallic orange glow paintjob, ferrari f40 rep wheels, full exhaust w/ no cats, koni shocks/springs, custom sway bars, polyurethane bushings, 4 spd manual with a fake gated shifter, and a pontiac grand prix v6 instead of the stock v6,ect ,ect ,ect. Car was bought for $3k, handled amazing, went like stink to 100mph, after 100 the headlights would pop up on their own and slow you down lol. Amazing first car. haha.
