How can you be certain they will leave you alone after the repo settlement and what is the best term to request they use when reporting to the CB?

I received an email today and if I send in 60% of the money owed within the next 10 days, they will stop the court hearing that is set for Feb. 15. My credit report will show paid for a lesser amount and the account at the Collectors office will show paid in full. I don't know if this is good or not but it seems like its the best I can do. I didn't contact an attorney due to lack of funds and at this time, lack of time.
