If you’re wondering what the differences are between the Mazda3 and Mazda6 sedans at Hendrick Mall of Georgia Mazda, then you’ve come to the right place. In the next few paragraphs, I will list for you all the differentiating factors between these two sedans and tell you all of the great reasons to drive either one of these Mazda Sedan Models. In the Mazda lineup, the compact Mazda3 sedan falls one size smaller than the Mazda6. The Mazda3 is a similarly delightful sedan with a more affordable price point, with more options, such as a hatchback version and available all-wheel drive. Passenger space and cargo room are limited in the Mazda3, as you would expect. However, the Mazda3 is a great option for those not quite ready for the larger Mazda6. In this comparison, we are going to look at how the 2020 Mazda6 Grand Touring 4-door Sedan lines up to next to the 2020 Mazda3 Preferred 4-door Sedan.


The Mazda 6 Grand Touring comes with a starting MSRP of $29,800 with the average price typically paid $28,307 and Invoice $28,136. As expected, pricing for the Mazda3 is slightly less with a starting MSRP of $24,200, the average price paid $23,483, and the invoice coming in at a low $23,143. The table below might give a better idea of how they compare side by side. Next, let’s look at the difference in size between the two popular Sedans, both available at Mall of Georgia Mazda in Buford, near Atlanta.
