my deceased mother's cts has been literally sitting in a garage [in South Florida] for the past 4 years; it's collected dust, cobwebs but no rust, at least, not that I can see. I'm thinking I might get it working again, although I recall it had been leaking oil when she was still able to drive the beast.  Not sure about the miles but it's roughly 69,500; after 4 years just sitting, the battery's doa, tires are shot, not sure about the transmission, but exterior/interior is in good shape.  I'm more worried about what's in the gas tank (she never used top tier gas), fuel pump, etc.  With the price of cars these days, is it worth getting this car running again, or should I just junk it?  I recall hearing Scotty saying that the 05/06 cts base was terrible, just a money pit; if true, then I'll just sell it as-is.
