Had a 2000 and 2003, both 2.5 manual, but been a Subaru owner back to the early eighties.
Bought the 2000 with 125000 miles at 3 years old, £3000. In four years/35000 miles I had to replace rear discs, a front caliper and disc, a few headlight bulbs and both front coils snapped, though I suspect speed bumps. Loved it.
Bought the 2003 at 4 years old, £8000, 68000 miles- had it for 10 months, no problems whatsoever. A lot more refined, but I felt more uneasy using it for carting bikes, rubbish etc around, and sold it for this reason.
Didn't bother calculating gas consumption really, but did hit 30mpg on a trip to Scotland once…
Very big in the back, bigger than a Mondeo, but load space isn't ideally shaped.
Took the first one to a Subaru main dealer when I got it for a service and to be checked over, then local garage after that- main dealer is exorbitant, even by comparison to other makes.
