Cause let say the bank loan 100,000 to the owner, paying 75% installment already mean owner paid the principle sum of 100,000 to the bank...mean, bank money, take back already their original loan money... not scared anymore...anything after is extra profit already...

Therefore no hurry to chase, or any urgent to tow perhaps, better coax the owner to pay the rest. Cause asking tow services, need to incur charges by the bank to pay tow fees, administrative fee, commission fees paid to TS, lawyer fees and various whatever all kind of hassles fees... so not worth it anymore for the bank =)
