My sister recently died from endometrial (ovarian) cancer. I'd rather she were still alive; I'll miss her for the rest of my life. If any woman reading this is diagnosed with this form of cancer, have it treated immediately. Radiation is probably the best; chemotherapy too often doesn't work against it. But I hope you never get it. While it's not the most common form of cancer, it's among the deadliest. Once it reaches your lymph nodes, it's just a matter of time. But this forum is about cars, and the one I inherited from her is a 2008 Chevy Impala LT with a 3.5 V6 and about 51K miles. The car is in very good condition, and so many of them were made that, when repairs are needed, parts should be easy to find. I've yet to see shop manuals (it's a 3-volume set) for it in used bookstores. The cheapest ones I've found online are $225. If anyone can link me to a digital version, I'd appreciate it. It has some drawbacks: it's not a Mopar, it's my first vehicle with a sideways engine, and it takes the dreaded Deathcool. Some of the electronic gadgetry is annoying; when the ignition is turned on, the headlights automatically come on, and will stay on until I turn them off. The left rear power window motor doesn't work. I've replaced this part on a '69 Imperial and a '73 Lincoln, but never on a Bowtie. I'll try to find one in a junkyard to see what complications it entails. It recently had the gaskets for some coolant crossover pipe replaced – there's a TSB on that, so that may need addressing again in the future. Design flaw, or done on purpose? And the Delco battery is about 6 years old. According to a July dealer inspection report (my sister always had the local dealer perform maintenance and repairs), it's losing CCAs. It still starts, but might not in freezing weather. This replacement looks interesting, but I can't find any reviews on it: https://www.meijer.com/product/home-improvement-auto/automotive/powercell-3478s-12-volt-platinum-automotive-battery/t1/t1-873/t2/t2-10052/71373347250.uts There are no Meijer stores near where I live; in fact, I don't think there are any south of the Ohio River. So, if it dies before the warranty period is up, I'm stuck. My brother has a Costco card, and we saw today that they have Group 34 Interstate batteries with 800 CCAs for $83 plus tax and exchange. I'm leaning toward purchasing one of them. Reviews are encouraged. My sister had OnStar, AAA, and towing insurance, which seems like overkill, especially if she didn't use any of them. OnStar is too much like Big Brother, plus it's over $300 per year. Her AAA membership is good for 3 more years; if they'll transfer it to me, I'll use them and drop OnStar when it expires next month. Can an OBDII scanner be used on this car, or will I need something newer?
