I lived in my Grandmother's house after she elected to move into a retirement community. When she quit driving (at 87), we parked the car in her/my garage and I drove it fairly often. It was a late 80s Cadillac and it was huge. I once hauled a 6 foot tall Christmas tree in the trunk of that thing.
I usually don't name cars either but I do call my husband's truck "Truckleberry" because it is this weird purplish blue color that is exactly the same as a huckleberry.
