I'd try $10k and state you'll take offers. Sounds like a good thing. A rust free HZ Kingswood van body has to be worth in excess of $3k alone, as that is way less than you'd save doing rust repairs. Add on GTS guards, dash and good doors and you are close to $6k already as a car to wreck.

GTS guards won't be factory fit though, if they were there new they will be dealer fit. The rest is standard or normal options for a Kingswood albeit rather rare especially 202 console shift auto and integrated A/C. It should be Jasmine Yellow too being a HZ unless a CTV order.
