Everyone has a different view on vehicle service, the availability of competent, reliable and fairly priced services for any make of car is a real variable for most of us. Individual actual and perceived needs also differ greatly. Weather you are interested in your vehicle or indifferent also enters into the equation, as well as how long you plan to keep it. If a vehicle is leased, or short-term (2-3 years) ownership, I'd generally do the factory reccomended services to satisfy the requirements of the lease and to keep it in reliable operating condition. Owning it and planning using it for 50-75k miles or longer as I usually do, I have my own set of maintenance standards, somewhat in excess of factory requirements. Based on a 25 year career as a Biomedical Technician, maintaining medical equipment, I understand the MTBF (mean time between failures) formula, in that most failures usually occur in the last third of estimated service life, (that includes fluids, batteries, tires, etc) I find that better maintenance using quality parts usually equals longer service life with increased reliability. Earlier, more frequent service for me translates into peace-of-mind.
