I believe that a car guy is anyone who is passionate about cars who knows at least the basics.
I also believe there are different types and different levels of car guy.
Lets take me for example, I’m very knowledgeable about the subject, work in the trade, own 3 trucks and have a decent amount of experience.
However, I tend to be the most passionate about the old stuff. I am a classic car and truck enthusiast whilst being and all around car guy.
It’s just when I sit in the seat of an old car or truck, I get more of a “feeling”
Even my young brother went crazy about my 55′ Chevy truck. He took pictures and sent them to all his friends he loved it so much.
When anyone can get that excited about any vehicle, they have some car guy in them.
