Requiem for a Saturn

My 1996 Saturn SL 1 with 52K miles is a salvage. I bought it in 1997 with about 25,000 miles on it and it ran great for years. And then disaster. In the past two to three years, the car has a newly replaced alternator, radiator, brakes and rebuilt engine. It ran again well for a short time but the service engine light wouldn't go off with the rebuilt engine and as soon its the warranty ended, the car stopped working. It turns out, 1996 Saturns have lemon engines. There was even a limited recall on the engines because of leaky head gaskets; I was notified of this by the manufacturer but I missed the recall in a series of wrong turns. Saturn would only service the car within 6 years or 100K miles (which ever came first) it if it had certain symptoms. I drove the car so little, the problems only showed up after I put more miles on it. And by that time six years had passed and the recall offer ended. Despite my requests, I couldn't get Saturn to fix it or the mechanic who sold me the second 1996 bum engine to fix the rebuilt engine. So. At this point the car isn't running. I've managed to get by without a car for a year or so. The car's Blue Book value is $2450 in excellent condition and $1750 in poor condition -- but only if I get it running again. I've been offered $500 by a dismantler. At this point, my plan is to sell, cut my losses and move on but before I do, I wanted to toss this question out at the 11th hour: is there any sense at all in fixing it? Or is time to shalom this baby?
