The only vehicle I, or anyone in my family, ever named was a '66 Chevy Pickup we had when I was a kid that we called "Ol' Blue". There wasn't a single body panel on it that wasn't dented in some way. The hood had flown up while driving on multiple occasions and was held down with a short piece of chain. It had been run into by numerous farm implements. The windshield was one big spiderweb of cracks. It was an all-purpose workhorse. It had a big diesel tank in back for refuelling tractors. it had removable racks that mounted on the front and rear bumper for moving irrigation pipe. We had a special wheel with a spindle welded on that we would put on the rear wheel that we would then put a spool on to roll up electric fence. As far as I know, it's still out on the farm somewhere "rusting in peace"
My 3 yo son named our current vehicles:
The Contour is called "The White Car", or just "The Car".
The Sienna is called "The Red Van" or just "The Van".
