I've always had a weakness for naming machines. Don't know why, it just happens.
Seems like the good ones that stick around forever just become family. My '68 W250 was my daily driver for 10 years. It was grey therefore became "Grey Ghost". It wasn't very sneeky though.
My Jeep, who is resting in dry, salt free comfort out in the shed has been mine since 1980! My first legal street vehicle. He was only 4 years old and was showing signs of rust then. 254,000 miles later and he's still my "Jeeper". Not rusty anymore either! Good Lord, 26 years, I'm gettin' old!
My current Dodge is well... "Whistle Pig" like his older brother also grey and still not very sneeky!
