I drove my 2007 Subaru AWD in snow a while ago and that Colin McRae sideways bro shit was awesomeNo I wouldn't touch one with over 100,000 - AWD is good for driving in snow? bullshit I have a 2009 Subaru AWD and it's just as horrible to drive in snow as any other car. The car you have now still runs don't waste your money on a stupid machine that only gets you from A to B especially when the pricks in Sydney can't fucking drive for shit and are always damaging your car.
No need for the duplicate posts in other threads.
I would go for the Spec B, they are NOT the same car. The Spec B stands for Spec Bilstein which means they have the Bilstein struts, shocks and springs and handle much better than the standard car. If you're planning to mod the vehicle and add coilovers then by all means buy the standard car, if you want to keep it a stocker then get the Spec B.
