LOL, it is in my comfort zone to be prepared even though I was never a Boy Scout.

My first car was $650 Capri 4cyl and a year later I "upgraded " to an $800 Datsun 260Z. Needless to say, they both broke down quite often. My 3rd car lost a transmission on the freeway 40 miles from home. So, I've got a bit of an aversion to being left in the lurch that came naturally .

My Grandfather always had a box of spare parts for his 60s & 70s Chryslers in the trunk. It came in handy on vacation/ long trips as he dipped into it fairly often. Of course cars broke more often back then too.
