The University of Michigan’s Customer Service Satisfaction Survey is a respected index that the school publishes every 90 days. The most recent research focused on the computer industry, the home appliance industry and the automotive industry. On the computer front, Apple got the best rating. Compaq earned the worst score of any company. Compaq is going through a merger with HP, and that is usually a recipe for disaster, at least for a while. How about Internet services? AOL again got the worst score. You would think that such a high-priced service would at least offer help to its customers. But Clark recommends against signing up with AOL for Internet service. When it comes to major appliances, Kenmore is the best. In fact, Kenmore, Sears’ private label, got the best number of any other category in the index. The lowest household appliance brand was GE. As for carmakers, Lincoln-Mercury got top honors. Honda was next, followed by BMW and Toyota. The lowest score for customer satisfaction went to Dodge. The second worst was Ford. Just above Ford were Chevrolet and Jeep.
