Drive one and you'll understand Merc1.
Scoobs aren't universally appealling and the plethora of limited edition models causes a great deal of confusion in the market - particularly as they're often specific to a local market only.
What has to be appreciated is that these cars aren't mass-market and they're not intended to have universal appeal. They're aimed slap bang at the loyalists who desire ever-faster and ever more focused Impreza driving thrills. This is a seriously hard-core car and not for the faint hearted.
There are many of these legendary limited editions, the P1, RB5, 22B, S204, WRX STI Spec C Type RA (yes, seriously

) and now this RB320 to name but the best that come to mind and they're an all too important contribution to the high performance Impreza persona. These are cars that offer the enthusiasts a new level of Subaru dynamism for those that have outgrown their standard WRX's and STI's but don't wish to switch brands.
So yes, to the general public it's just another Impreza but to each of the lucky owners it's the definitive all-wheel drive point-to-point experience of a lifetime - without having to shell out twice as much for anything close.
