One study says one thing, another says something completely different. A customer satisfaction survey called the University of Michigan's American Customer Satisfaction Index was recently released showing American brands are falling in customer satisfaction. One reason may be rebates that add an air of lesser quality to some. But there was some good news. The biggest gainer in satisfaction was Lincoln/Mercury. Although that Ford owned company faired far better than Ford itself that came in second to last only to Dodge. Overall the study contrasts the recent J.D. Power survey that suggested American companies had gained ground on the imports in quality.
