The mileage windows when the 1993 Lexus LS most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, the 1993 LS is essentially still in its prime. Expect only routine fluid changes, tire rotations, and minor wear item replacements. Major issues are virtually non-existent.
