If you are going to use the car just for transportation then get the outback, but if you want to put some mods on the car then I agree with andy and get the GT. There is VERY limited aftermarket for subarus, mostly imprezas and a few things for the Legacy. But I don't think there will be anything for the Legacy outback. You might be able to get the SYMS short throw shifter to fit the outback but I don't know. Check out
www.spdusa.com and read through that site. He is really good about answering questions! If you want a performance car then I would say get the Impreza RS now or wait for a year until the (rumored) turbo Impreza and or the 6 cl Legacy comes out. Just my .02
