With LoJack dead in the US, what is a classic car GPS tracking alternative?

I agree with a $25/mo burner phone with free life360 app on it. It monitors location in real time for free , Also does speed and even history of driving with a cheap monthly fee. Tap a RUN feed for a battery charger so when its off its on internal battery. Only issue is that you got about 18 hours before the phone battery dies. It gets the location pretty close, I can follow my wife right up to the door when shes shopping, but my kid had it on his phone and it once told me he was 2 blocks off campus (he wasnt) but the app reported it. 5 minutes later it showed him on campus. Just a glitch but if your looking for a car in a garage or something, Im not sure if it would get you to an address, more like the street and 6 houses.
