Man, you're lucky. If I had a dad that liked cars, or could at least paint mine for me, I'd still have my '70 and be on cloud 9. That's great you had that opportunity and it's even better you want to pass that on to your kids.
My father, bless his heart and rest his soul, could hardly change his own oil let alone build a racing engine. Course, he committed sucide when I was 13 Y/O so he never got to see how I turned out, but if he were here, he'd prolly be kinda proud I guess. So you see, not everybody who's into Musclecars and the like even grew up with a father at all. Doesn't matter much, as my affection for the cars was born from going to high school with all the "Rejects" at the school. You know the ones, always wearing Flannel shirts, blue jeans worn paper thin, and work boots. We were the ones you youngin's today would refer to as the "Rednecks". ALL of these types had some sort of fast car that when it fired up and all were hangin' round BSin', you better hold your tongue and grab all the info you can for future use. This is what I did because I wanted to be in that "Elite" group known for those fast, and obnoxiuosly loud "Cool cars" that made the "preppy" kids think the worst of us. We were the fastest at the school. There was one of the rednecks that thought he would up his status and try to become a preppy when his pop bought him a shiney red 1965 Mustang. Could it get anymore cleche'?? Well, he decided to put "1fast65" on his plates. I decided to put "1fastr65" on mine, as I owned a 1965 Plymouth Satellite.
Of course, the inevidable time came when I was challenged to "prove" it. Right in front of the school. I did. At that time, I was finally "Accociated" with the "Redneck/cool guys" that had the badass cars. For me, I wasn't a jock, wasn't a preppy, wasn't in the band, and wasn't one of the "Smart kids", so all I had left was where I was accepted and that was with the gearheads. I couldn't have been happier. I had a job when I was 15 Y/O. EVERY penny went into paying my own insurance and buying racing parts. I also helped out on a couple farms AFTER my shift ended. Try getting a kid today to even put down his/her cell phone long enough to work....I remember tearing down my first cars engine and spreading parts out all over the garage. know what Mom said? "Oh lordy, well, if you drive it at all, YOU are gonna have to put all those pieces back together".
I built my own sh*t. (With help from my Automechanics teacher which later on, I told him he was kinda like the car dad i never had. Thought poor sap being a "Cool guy" was gonna get all teary eyed. I still see him every now and then and I still call him "Mr. Gray". Try getting a kid to do that these days even in the classroom. It all depends on who you decide to hang out with as to how much knowledge you gain for the hobby. If it's kids with texting on thier minds, then you won't go very far.
So you see, it really doesn't matter if pops helps or not, as long as you have a band of friends that are willing to help you out when you are stumped on your project, you can be a part of the "Cool gearhead" Brotherhood...
