Originally I had named my E46 M3 Heidi. After Heidi Klum, only to discover was I only not very clever but also one of about a bazillion other M3 owners who had named their car exactly same. After that discovery I didn't call the car any other name until one day I had decided I found a name that I felt suited the car. That name is Olivia, I probably started calling the car that regularly about 3 months ago and I like it a lot, so its staying no matter how much bad juju I may get for the change. (probably why my SES light came on the other day)
