First off i have an 06 USDM FXT.. after driving it for a year now here's my review of the FXT so far..
Pros:
2.5T Boxer (same as the WRX but not the same block as the USDM STi anymore)
Symmetrical AWD (for me this is the best but don't quote me on this though)
Ultimate SLEEPER (few drivers out there know how capable this vehicle is)
Reliability (as most subies are "recall free" again don't quote me on this)
Quality (Build & Engineering wise)
Handling (better than your so called SUV's out there remember this is an Impreza based "tall" wagon & be ready for slight understeer)
Acceleration (even with the 4EAT tranny im pretty pleased with it)
Safety (5 star crash test ratings)
Safety Ratings Safety Rating 2
Sunroof (damn i love that big sunroof)
Cons:
Suspension (a tighter suspension would be great like the one in the STi version)
Stock tires (i don't like the stock tires as they tend to be very whiny in certain conditions)
Backseats (not very comfy if you have a big family or have kids but i think they're ok for an average "asian" size)
Steering ( a quicker steering would be awesome like the one in the STi but i guess that's just me)
Wind Noise (well what do you expect with pillar-less doors)
Paint (most subaru paints are not that awesome)
What's good with Subaru's is most of their cars share the same platform and parts.. with the 04-07 Forester you can share virtually any parts from the 02-04 WRX/STI as the 05 and up STi has a wider track and diff lug pattern.. but otherwise everything just bolts right on to the FXT with minimal to no modifications needed.
well this is "only" from an FXT owner so whatever decision you'll make goodluck..
