We've finished testing our 2018 Mazda6. We discuss our final impressions on the midsized sedan and where we think it stacks up against its competitors. We answer a number of audience questions this week, including one about our best advice when negotiating the price of a car with a dealership. We also talk about the Subaru Ascent recall, and remind Volkswagen diesel owners that time is running out to file a claim for settlement compensation. | Consumer Reports
