When were you bitten by the car bug??

Shoot,
Probably around 5 or 6 y/o. We had Tonkas Hotwheels, and model car Amt and whatnot. I thought it was so cool that a pile of parts could be turned into a car. (Ha ha still do) .
I suggested at 10 years old when the family VW square back motor blew, that we “just get a motor for it” and do it ourselves. Pops said no. Sold that for 400 bucks. Still kills me
BUT it wasn’t until Gramps took me for a ride in a big 390 equipped Ltd, and casually, did a Smokey burnout leaving the Shell station that I was hooked.
Still remember the smile on his face, the sound of the 4 barrel opening up. Maybe 12 yrs old. My old man and family were never car people.
