No offense, but I would imagine if you asked about one hundred male 25 year olds if they could change their own tire in an emergency about 75-85 would answer no. My generation didn't get auto shop / wood shop / metal shop in high school due to cost cutting. My generation had fathers that worked in white collar jobs about 70 hours a week. I was lucky if my Dad would be able to make it to my hockey games, let alone take me out to his car on a Saturday and show me how to change a tire. Here's another shocker: I have no clue how to change my own oil. We live in a demand society where you can take your car anywhere and have it serviced by anyone. There's a lot of people who have no desire to service their own vehicles and until I bought my Crossfire, I have always *hated* my car. I've never had a car I actually enjoyed to drive. They were always utility vehicles that got me from point A to point B and cost me $2,500 and I drove them into the ground. I love my Crossfire and finally have the desire to learn about how it works so that I can service it and not have to take it to someone I don't trust.
