How would this play out in a separation?

I’m going through a separation, where my wife has taken a business we co-own but she runs to herself, which I’m able to make peace with really, but here’s the kicker.

We have 2 cars, one bought in her name, cash down (our first car post relocation, which we both contributed to buy btw) and the other is financed, in my name.

The finance has almost 4 more years to go, but she has said she is not interested in any of the cars and wants to

1. Sell and split the first car.
2. Get her contributions so far on the car note back.

My understanding is that the car is a liability and we have to treat it as a debt, but I am not sure what the right approach to this is. I’m trying to sort this out without any drama, but seems she wants to make this as expensive as she possibly can for me, despite all the abuse.
