1987 190e

Please help! I gave our son my old & beloved 1987 190E, 2.3 MB for a present after he made the Who's Who in H.S. Students, and.... I went to open the hood to show him how to check all fluids, and the cable that goes from the inside of the car to the hood release broke. So now we can't open the hood at all!! Please help!!! He wants to go to a graduation party this Friday night with his "new" MB and it needs an oil change, and his father won't let him go unless the car has been serviced.
