A month or so late, but figured I'd add my $0.02...
Daily drove a 2002 5-speed WRX Wagon for somewhere around 4 years and 40k miles.
The good:
-A beast in the snow, even on worn all seasons
-Comfortable on long trips, swallows a lot of stuff with the back seats folded down
-2.0 motor really is the exception when it comes to issues notorious to turbocharged Subaru's. I beat the snot out of mine everyday and it never left me stranded
-Loved driving it. Filter, canned tune, up-pipe and eBay turboback and it ran 14.4's with some garbage 2.5 second 60' times
-If you don't count gas, it was pretty cheap to own. Insurance for the wagon was considerably less than the sedan. I loaded up on some cheap Purolator oil filters that were supposed to be identical to the OEM filter, and Rotella T6, which always seemed to be on sale and with some mail in rebate at my local department store. It probably helped that I owned it in between timing belt change intervals, though.
-They hold value tremendously well, and at least in my case, are super easy to sell
The bad:
-Gas mileage. Given what it was, I didn't mind it on long trips, where I'd get 25-28MPG. Otherwise, on my 100% city commute and generally 95% city driving, I'd get a little over 20 most of the year, and then it would dip below 20 in the winter. At the time, premium was up around $4/gallon, which ended up influencing me to get a different car to DD.
-They like to corrode. And not just the body. I had to replace my rear diff after 12/13 suburban Detroit winters and 180k+. A lot of the rear suspension/driveline bits were fused together and I ended up having to replace a lot more than just the diff. I also needed front CV boots and would try a couple times a year to free the axles from the hub without success. After I stopped DDing it, this was kind of what influenced me to sell it.
-Even though the owners manual says you can use the space saver if you get a flat, don't do it.
-Don't do donuts in the snow with the steering at full lock to one side.
-The cup holder high up on the dash sucks if you have the heat on but want to keep a drink cold.
I miss it from time to time. If I had to do it again, I'd buy one that's never seen salt.
