Run a full scan, check for open recalls/campaigns by VIN, confirm oil level and service history, and inspect for modifications (intake/tune/exhaust) that may change maintenance needs.

3) Manual or CVT (SPT)—which is safer long-term?

Both can be fine, but the manual’s “risk” is clutch wear (especially if launched/tuned). The CVT can manage torque with protective strategies and is sensitive to heat. Choose based on your use-case and maintenance habits.

4) My screen goes black sometimes—what’s the best move?

Document the behavior (photos/video), check software level, and ask about coverage/warranty extension for the head unit.

5) Do I need shorter oil intervals than the dashboard suggests?

If you do short trips, winter driving, spirited driving, or track use, shorter intervals are a smart turbo habit. Also: check oil often.

6) How do I check for open recalls?

Use Subaru’s official VIN recall tool and/or NHTSA’s recall lookup.

Best for Drivers who want a fast, all-weather performance sedan with strong tuning potential and daily usability.

Watch-outs ⚠️ Infotainment/head-unit glitches and campaign updates (EyeSight/PCV-related) are the most “paperwork + dealer visit” type issues—verify your VIN is up to date. :contentReference[oaicite:28]{index=28}
