Is it a blow to a guy's ego if his woman knows more about cars than him?

Lol i think those times have passed. I love Jeeps and Mustangs especially and before I was sick rockcrawling and anything outdoors. I used to attract quite a bit of attention up under the hood when something went wrong. I couldn't always reach so I would climb up. Not long ago I had a guy friend drooling because i knew all about air fuel ratios etc. I used to put on my little overalls and a tshirt and help my daddy tinker with cars. I soaked in those lessons like a sponge and in some ways know as much as, if not more than my brothers.
