What the data shows

This 2021 WRX appears well-maintained with a single owner and frequent oil changes, but the extensive modifications — including a pro tune with crackle maps — introduce uncertainty for long-term reliability and emissions compliance. Budget about $500 for the upcoming 60k service (spark plugs, fluids) and another $300-600 for likely intake valve cleaning. The price is at the top of the market, so ensure the condition and mods justify it. Among sport compacts, the WRX offers strong reliability but aftermarket modifications can shift risk.
