My Blazer has almost 100,000 miles and has required very little maintenance over the years. I asked for a thorough review of its current condition and recommended service. I was given a detailed explanation of service needed, but also a "priority" list of the most important repairs if I chose not to do everything as recommended. Since the car has relatively low value (due to its age and mileage), this allowed me to choose the items that could compromise safety or near-term reliability and defer some others.
