Wives/Girlfriends = Car Women
In reading the replies and comparing them to the poll results so far, I think it's pretty sad that most don't have support / help from the ladies in your life.
I realize for some the garage is an escape zone ... but also realize those girls are missing out on so much: learning something new, spending quality time with their man, making something better or faster with their own hands, and having that awesome feeling of pride and accomplishment when you step back and look at what you've done. Sure, ya get dirty -- but it comes off. Dawn isn't just for dishes. :-D
On the flip side, I've had a few boyfriends over the years who weren't into cars and weren't interested in learning how to help with mine, and something was just missing in those relationships. Having hobbies your partner isn't interested in is also healthy to some degree, but when cars are such an important part of your life you don't think of it as just a hobby. I'm glad I've got a car guy and probably wouldn't have it any other way. :-D
