legally the drive is liable, if you have auto insurance, the insurance will cover for the damage. If you don't have the insurance then ask if the car owner has the full coverage insurance. If he does then it will cover for the damage. 
Remember if you have auto insurance, you and you car both are insured and if you drive your friends car and wreck it, your insurance has to pay for your friend's car.
I don't know whether you have another car and a insurace with it, if you do, your insurance have to pay for the damage.
