Top-Rated 2018 Coupes and Convertibles in Quality
The annual J.D. Power Initial Quality StudySM (IQS), conducted for over three decades, is the benchmark study for owner satisfaction with new-vehicle quality. The study, which measures owner-reported problems with vehicle design and with defects during the first 90 days on the road, is based on responses from more than 75,000 verified new-vehicle owners.
To help consumers research and shop for a new vehicle, J.D. Power has developed Power Circle Ratings, based on data results that reflect and sum up IQS findings in an easy-to-use graphic format.
This buyer’s guide highlights the top-rated coupes and convertibles for 2018. Each of the models earns 4 or 5 out of a possible 5 Power Circles in initial quality during the first 90 days of ownership.
