Getting Divorced. Both Cars Are In Wife's Name. She Wants To Keep Both Of Them.

I live in Michigan. Wife and I separated last June and are now trying to start divorce process. Both of the cars we had during the marriage are in her name. One we bought together from her parents. The other was a wedding gift from her parents. Basically, she either wants the car I use or to give her an equivalent value, which she somehow appraised $7.5k for a pretty beat up 2004 jeep grand Cherokee. She refuses to talk to me about any of this so I can't even try to negotiate with her. I don't even know why she is doing this as it seemed like she wanted to just get the divorce over with and go our separate ways. I can't afford a lawyer. Idk what to do or how screwed I am
