The 12V still bricks the car
No engine oil. The 12-volt battery still runs contactors and computers. A silent Tesla, Bolt, or Prologue is often a $200 12V, not a high-voltage pack.
The car is dead in the driveway. No screens. Someone already quoted a battery pack. You need a rested 12V voltage first.

Expert notes
12V rested · V
Contactors need a healthy 12V. A pretty rest number can still fail a load test. AGM vs lithium 12V is a SKU, not a guess.
Cabin / HEPA
Tesla and some others use a HEPA path. Aftermarket is not always a Fram number. Confirm the refresh SKU.
