The price reference is the median of configuration medians, not the median of all active cars. Each configuration has equal weight. Configurations with at least 3 priced listings are used when available; otherwise the reference uses the configurations with a recorded price. Model years, mileage and condition vary.

The 2.5L 4-cyl Legacy: common questions

Which Legacy years have the 2.5L 4-cyl?

2010–2025 — 14 model years in our VIN decode, across 123 factory configurations and 153,716 VINs.

What does a 2.5L 4-cyl Legacy cost?

$14,701 is a configuration price reference: the median of configuration medians, with each priced configuration weighted equally. It is not a listing-level median or a valuation of an individual car. The year-by-year ladder shows VIN and inventory counts; its links open model-year price reports covering all engines.

Is the 2.5L 4-cyl turbocharged?

No — every configuration in this family decodes as naturally aspirated.

What is the engine code, and does it matter?

NA, U5 — the code the VIN decodes to on the configurations on this page. It matters when you order parts or read a service history: the same displacement badge on another model can be a different code with different outputs.
