My family buys used cars, usually in the 3-5 year old range, we do our own repair work, and drive everything for 10-15 years. It's usually close to 15 than 10. We drive them until they drop.
I figured it out one day and the lifetime TCO has been about $100/month per vehicle.
We really, really need legislation that says advertised features can't require an ongoing subscription. The whole scheme of giving the original buyer a "free trial" that lasts long enough that they'll sell the vehicle is just a tactic to seek rent in the secondhand market. The thing is, there are a lot of people buying second hand because they don't have money to waste.
How do you pull yourself up by the bootstraps if the bootstraps require a subscription you can't afford?
