i need to get rid of it but im way upside down.

3rd cyl. has no compression. could be an open stuck valve??
i wont know until they open it. I'm not sure it has become 3.0 time. or what my options are. I would like to keep it (cause i won't be able to offer a competative price if i sell it.) but i am willing to sell it at take over payments or even for what it's worth and i'll take the hit for the upsideness.

any ideas on how much damage do you think could've been caused. and how much $$ am i looking at for repairs?
and the car still has warranty... do you think i can pass it off as a warranty repair?
