1984 Porsche 928 928S Auto. Trans. Not running pre S4 GT GTS model

1984 Porsche 928. The engine is locked up. Not sure what the problem is. This car is missing the front spoiler, he sunroof motor cover/panel and the battery, therwise complete. 104,055 original miles. It has been sitting for almost 10 years. Both seats work/move in the Six different directions as designed. The windows and sunroof don't move, wonder if they are on the same fuse? It has the original "Slate Metallic Blue" Paint with clear coat issues. The body is 98% Laser straight. The chrome is flaking off the wheels. The interior is all there and looks rough is some areas. It does have the original collapsible spare tire, n aftermarket 12V Air pump, nd a partial tool kit. No books, anuals or service records. Comes with a clean/clear Calif. title. The tires are about 60% and are weather checked. I know you 928 Buffs will have a Dozen and One questions and I will do my best to answer them. Selling AS IS for parts or repair. Local pick up in Medford Oregon. Medford is 30 miles North from the California border, -5 runs right through it. Please ask any ?'s before bidding, r better yet email me your phone # and will call you back. Thanks.
