MG MG4 vs Mazda 3
Data verified April 2025
At this driving profile, the Mazda 3 is the more economical choice over 5 years in New South Wales.
Running only 15,000 km per year in New South Wales, the MG MG4's higher purchase price doesn't fully pay back through lower running costs within 5 years. The MG MG4 costs $76,769 in total versus $63,331 for the Mazda 3 — a difference of $13,438. The numbers don't reach break-even within this holding period. If you drive significantly more km per year, or if petrol prices rise substantially, this comparison would shift. The MG MG4 still avoids around 619 kg of CO₂ over the ownership period.
The economics don't stack up at this driving distance — increase annual km or extend the holding period to change the picture.
