For your 2020 model year comparison, both the Mazda3 and Honda Civic are excellent, reliable choices with low maintenance costs and strong value retention. The data shows the Honda Civic has "extremely positive sentiment regarding long-term reliability" and is consistently described as one of the most reliable cars with minimal mechanical issues. The 2020 Mazda3, part of the current generation, receives praise for its upscale interior and driving dynamics, though some criticism exists for its powertrain being viewed as outdated.

Between the two, the Honda Civic likely has a slight edge for your priorities. Its reputation for reliability is more uniformly positive across generations, and it is specifically noted for low running costs and strong value retention. The Mazda3 is also very reliable, particularly with its 2.5L engine, but the Civic's track record is the benchmark in the class.
