My 2003 A4 Quattro, has been sitting for approximately a year and a half, the car had been towed which cracked the oil pan. All of the oil has essentially leaked out of the car. What should be my primary concern? What is the best plan of action to get the car back on the road? The car has 110,000 miles on it with the original timing belt. Any advice/help you can offer would be greatly appreciated ...
