I've named all my cars - I really believe it makes a difference if you bond with your car. As laughable as it sounds, things have happened with my cars that reinforce this belief.
car names (over the years - first two cars weren't named)
1986 Izuzu iMark - "Tojo"
1985 Volks Jetta - "Maximillian" (Max for short)
1980 Volvo 244 - "Lars"
1976 Volvo 245 - "Thor"
1997 Saab 9000T - "Sven"
"Tojo" managed to repair it's own transmission and drive around without a clutch for several days (broke clutch cable). <--those are seperate incidents.
"Max" managed to last to 265K miles, with oil changes every 40K(!), and drove the last 75K with a smashed front-end and a radiator that looked like a "V". I eventually donated it to a friend for an art project, and it just sat around for over a year. When I came back to town, I tried to start it for a laugh, and it started immediately.
"Lars" managed to drive 2500 miles in two days, with over 200K. Also managed to make it 200 miles with a leaking radiator and down-a-cylinder (to only 3), so I could make a New Years Party. Was retired to city-only car after that.
"Thor" and "Sven" have always been well-behaved and w/o incident (knocks wood).
