I have an 03 SVT 2 door sonic blue that I purchased new. It just hit 50,000 miles. I've done an oil change religiously every year for the last 15 years since it only sees about 1,000 miles a year. Before that it was every 5,000 when I was driving it more frequently. All the fluids are original except brake fluid which I've changed about every 5 years. I don't drive it all in the winter. So what's the best things to tackle this winter?
