Which holds its value better, the Mazda CX-30 or Subaru Forester?
Mazda CX-30 has the stronger five-year result in this comparison. The Mazda CX-30 is estimated to retain 72.2% of its original value after five years versus 71.6% for the Subaru Forester, using the same 2026 observation cycle. The difference is 0.6 percentage points. This is a model-level curve, not an appraisal for one VIN; trim, mileage, condition, options and location can change an actual resale price.
Is the Mazda CX-30 or Subaru Forester cheaper to buy used?
Across the model years in this dataset, the Subaru Forester has the lower average median asking price at $21,871, about $1,963 below the Mazda CX-30 average. That broad average is a starting point, not a like-for-like quote, because each model can have a different year range, trim mix and mileage distribution. The year-by-year table is the better place to compare vehicles of the same age before checking listings near you.
Which is less expensive to maintain, the Mazda CX-30 or Subaru Forester?
The available model data does not provide a complete annual repair-cost estimate for both vehicles, so this page does not name a maintenance-cost winner. Use the RepairPal ratings where shown, review recalls and complaints in each model-year guide, ask for service records, and budget for an independent pre-purchase inspection. Age, mileage, powertrain and previous maintenance usually matter more than a single broad reliability score.
How does CarResaleValue compare the Mazda CX-30 and Subaru Forester?
CarResaleValue normalizes observed used-car asking prices to a standard 12,000 miles per year, applies a 5% asking-to-sale adjustment, and compares the result with original MSRP references. A smoothed retention curve produces the five-year estimate when the data contains an observed five-year cohort. This page combines 2,666 listing observations across 17 model-year records, then adds EPA fuel economy, NHTSA safety data and RepairPal ownership indicators where available.
Comparison methodology
This page combines 2,666 listing observations across 17 model-year records. Asking prices are mileage-normalized to 12,000 miles per year, adjusted by a 5% asking-to-sale estimate, and compared with original MSRP references. Five-year figures use a smoothed curve only when an observed five-year cohort exists. EPA, NHTSA and RepairPal fields are shown independently and may cover different model years.
