Acceleration is moderate at first, then strengthens considerably. The ride is very comfortable and the car responds quickly and surely to sudden changes in direction. The hard top convertible is a real plus. Quiet as a coupe when up and very easy to get up or down. Quality is expectional. No repairs needed thru the first 35,000 miles. Maintenance costs are very high if serviced by the dealer. The summer run-flat tires that came with the car were useless in winter, wore out in about 25K miles and were expensive to replace at $300 per tire.
