Ten years ago today I drove off with my brand new Toyota Prius. At the time I wasn’t sure how long I would keep it, but I generally keep cars for as long as they last. Ten years and 218,860 miles it’s still getting me where I need to go.

Three years ago I had to replace the large battery and that was a few thousand dollars. But other than that, a few minor repairs, and routine maintenance, it’s been great. The first battery lasted seven years and when I replaced it I assumed I’d keep it for the life of the second battery. There’s no way to know how long this battery will last, but assuming I have four years left, that may do it.

I’ve averaged 21,886 miles per year (and assuming all trends continue) the odometer will read 306,404 on March 17, 2020. At that point it will be a 14 year old car and I don’t imagine I’ll pony up for another battery.

But who knows?
