Look, Subarus are ugly. They always have been. Who cares? Motorsports are not beauty contests.
That said, I actually like the looks of my 2009 WRX. I didn't like the wheels or the stock grille when I got it, so I changed those. I added the factory Sport grille and some Rota Torques to replace the heavy and narrow stock wheels. Now it looks like a 1st gen Mazdaspeed 3 with a hood scoop. Nothing wrong with that!
Example:
On the new Legacy:
It's really hideous, even for a Subaru. the 6-speed is NOT the STI 6-speed, just a version of the WRX 5-speed with one more gear and different ratios. They put the turbo under the engine on these, which on paper diminishes lag a bit, but I'd rather have it up away from the road. The GT is half baked and makes similar power to the WRX, but in a much larger car. The 05-09's are cool though, especially the super rare 05-only GT manual wagons.
On buying a used STI (or any used turbo Subaru):
Be VERY careful with what you are buying. Most dealers would have absolutely no clue if a trade-in was formerly modded. There are threads every day on the Subaru forums with people either returning their cars to stock for a trade-in or buying a car that they thought was nice only to inherit a ton of problems. This is the reason why I bought new when I bought my 2009.
