My question involves an auto loan or repossession in the State of: CO

Hi all! Thanks for reading my post. We are considering voluntarily surrending our 2002 Dodge Caravan. We are upside down on the loan to the tune of around $2,000. I was just laid off from my job and we can't afford the $350 monthly payments and don't really need the van anymore. Having read the other posts, I assume that if we do this, the loan company can sell the vehicle at auction and then come back at us for the difference. If we were to file bankruptcy would this get rid of this debt? Also how do you talk to the loan company about this? Thanks!
