My car is currently in the shop for repairs. There's nothing like having no car to remind you of how much we take that sort of mobility for granted.
I appreciate having a vehicle of my own more than most, I imagine, simply because I get motion sickness. I also really like being in control, though--a personality trait I try to keep in check to varying degrees of success. I've had access to cars since I first got my driver's license, almost immediately after turning 16.
I don't consider myself a car guy--I don't work on them, I don't have any brand loyalty, I have no interest in modifying my car, etc--but I believe each of my vehicles, past and present, have factored into my identity.
