Four. One is my son's and he shows up for oil changes. One has a special limited-use insurance package.I keep it around as a backup car as my wife commutes 50 miles per day and I'm often in Calgary, working. Need the security of the extra car in our rural area.
My Volt and my Impala, my Mom's Mazda 6, Dad's Hyundai and hif gf's CR-V. I service my sister's Saturn when she remembers, which is never, plus whoever else needs their car worked on. That's in addition to the several hundred cars a month I service at work!
