Price for Falcon GDA WRX is around 1.1 million to 1.35 million. Falcon GD STI (not original GDB) is around 1.35 million to 1.7 million. Depends on condition and options.
I enjoy driving a Subaru more than an Evo, it felt more connected to the road. However, Evo is much faster and cheaper to modify. Used to own GDA WRX, GD STI, and Evo 6.5. Now, only drive Jazz.
