Go after his suv. Sue him and if he has no cash, see if you can use his suv as payment and part it out. Bound to be some sort of recourse for this shit.
Seize his personal property maybe? They can put a hold on property in a divorice setelemnt, why not here?
I am probably using the wrong legal terms, just conveying the general idea. Talk to a quality slimeball lawyer, they sould be able to help.
