Traded in '02 WRX on '08 Legacy GT. The GT is roomier, with much better features (leather, sunroof, auto AC, auto trunk, XM, auto mirror), much quieter, and only cost $2K more than my WRX did 6 years ago. As quick as my WRX 0-60, same cornering G, but simply not as fun to drive. However, this is a much easier car to live with (quiet), and everybody who rides in it loves it. Quality is same or better than WRX - outstanding. Other than for clutch, never had a problem with the WRX in 75K miles (never even touched the brakes!). I'm looking forward to a similar experience with the Legacy GT.
Satellite radio just became a "must have" feature in my family. Black leather looks and feels fantastic. It's so quiet and refined, and without a spoiler, it's sneaky fast.
Engine gets a bit weak after 6000 rpm, and only revs to 6500, leaving on 3K-6K of strong acceleration; needs another 500 rpm, and better high-end torque (how about the STI engine). Suspension could be firmer; too much body roll. Seat backs need bigger bolsters. (Tough transition from extrovert WRX)
