2003 Subaru Baja: Buy or Avoid?

The 2003 Subaru Baja is a uniquely styled and capable crossover that offers robust all-wheel-drive performance and decent utility for its size. However, its Achilles' heel remains the notorious 2.5L EJ25 engine's head gaskets, a critical maintenance item that demands thorough inspection or proactive replacement to ensure long-term dependability. If this major flaw is addressed, it transforms into a highly distinctive and reliable vehicle for niche buyers.
