I'd just do maintenance items that can deteriorate from exposure and time. My 2004 has 52,000 miles on it and I've only changed the serpentine belt with a Goodyear Gatorback, flushed and replaced it's coolant, brake fluid and done it's oil/filter changes and greasing it's drive shafts on a schedule that takes into consideration short drives and winter weather. I do these myself because I enjoy performing them and have a garage to do them in. I'm not concerned with the timing belt just yet because I feel it's age isn't a factor in the Minnesota climate. Other members may have differing opinions but these have worked for me over 50 years of vehicle ownership and a variety of types of cars/trucks.My '04 V-8 has about 32,000 miles on it and I'm wondering if I should do anything to it other than the regular 30K service seeing that it's almost 7 years old.
