Subaru Impreza WRX ST.
What to Check Before Buying.

The Subaru Impreza WRX STI suits enthusiast drivers seeking exceptional all-weather performance and rally-bred handling, though running costs demand careful budgeting. This turbocharged four-wheel-drive performance icon delivers outstanding grip and driver engagement, making it ideal for keen drivers who appreciate mechanical involvement over luxury refinement. However, the 2.5-litre boxer engine is notorious for high fuel consumption (typically 25-30mpg) and requires premium unleaded, whilst insurance sits firmly in the top groups. When inspecting used examples, always check for complete service history with evidence of regular oil changes, as the turbocharged engine is sensitive to neglect. Listen carefully for rumbling noises from the boxer engine that could indicate bearing wear, and inspect the clutch operation as replacements are expensive. Examine service records for cambelt changes (required every 60,000 miles or four years) and check for any modifications, as poorly executed aftermarket tuning can severely impact reliability. The STI's enthusiast ownership often means spirited use, so thorough mechanical inspection and HPI checks are essential before purchase.
