2004 Subaru Forester X AWD 4dr Wagon (2.5L 4cyl 5M)
This car is great except for fuel and maintenance costs. Plugs only last 50000 and cost 300-400 to replace due to complexity of the flat design and the turbo plumbing. Most recently I had a raw gas odor requiring replacement of fuel hoses which required removing the intake manifold for repairs. Also found an air turbo intake hose with a hole in it ($100).
Performance, fun to drive.
Simplify the intake manifold system for maintenance. Easier spark plug replacement.
