Should You Buy the 2003 Subaru WRX?

2003 Subaru WRX Mileage Danger Zones

High Risk & Refresh Zone
Beyond 100k miles, a 2003 WRX is entering a phase where major engine components may fail, or require extensive preventative replacement. Assume many systems will need attention or replacement, unless a comprehensive rebuild has already o…
