I had a 2010 prior and sold it at 120,000 miles. Very reliable car and had minimal rust after 9 years. Current 2018 hasn’t had any issues in 13k. This gen of mazda3 has terrible road noise. At least here in Texas, 75mph in Mazda3 was a nightmare. Same numbers with less weight will net you quicker acceleration. The Mazda6 feels quick, but with the 2.5L, the Mazda3 feels like a little rocket. It'll do 0-60 in the high 6 second range, which is extremely impressive.

In this test, the 2021 Kia Forte makes a good case for itself, with a lot of features in a decent little sedan for under $20,000. If it’s a bargain you seek, then the Forte j7E3y.
