My truck Jill is thirty six years old. I don't know the formula, but I know one vehicle year is longer than a human year. Say it's just two, Jill would be 72, three she would be 108.
I continue to maintain her as she ages, like I do myself. Buying another vehicle is completely off the table and I need to get around. I need to be able to get to the stores here!
Although, if she dies, I could just say screw it, go on food stamps and use the local ride share services offered by the Senior Center to get to Krogers. I could even have everything delivered.
