Yes, if you are sued and lose and still do not pay, then it is possible that a vehicle ncould be seized by the sheriff (or other court officer) and sold for the benefit of the creditor, or that your wages could be garnished. If the value of the ATV which was repossessed is less than the then-outstanding balance of the loan or other amount you owed, you may be sued for the difference. You may wish to contact the creditor and see if you can't voluntarily work out a payment plan which you can afford.
