$500 · Oldsmobile Achieva 2-door coupe 1994 *possible parts car

I have had this car for 6 years and have created a lot of great memories with it, unfortunately our time together must come to an end. I mainly used it for errands during most of that time, however the cost has become too great for me to keep it. Positives: When bought 6 years ago it got fully inspected and repaired up to code. Tires 6 years old but in good condition. 2 year old A/C compressor bypass pully and belt tensioner assembly. Odometer is low for a car its age. Is fairly unique (having not seen another Oldsmobile in the 6 years I've had it). Good on gas (has half a tank now) and has had it's oil changed recently. Negatives: Battery (6 years old) not holding charge, possibly needs a new one or there is a problem with alternator. Has several engine leaks (intake manifold, valve cover gaskets, transmission cooler lines). Muffler has large hole and creates a lot of noise. Seals are not great, water gets in all the time without some kind of cover. Gas cover door has trouble closing and has minor dents. Driver side window has trouble rolling up. Price is negotiable, thank you for your time.
