Firstly forgive my complete lack of knowledge, just brief question, how as complete newbie would you tell the difference between the Impreza WRX and the WRX turbo? from what I can tell appart from a few minor accessories being present on the turbo and not the standard version there is certainly no noticable difference in performance.
I only ask this as I would assume that only the turbo version would have the bonet scoop or am I being a complete fool?

 

I've never heard of a WRX Turbo as far as i now all WRX's have a turbo.

 

The WRX is the turbo.

Depending on the year, the 3 basic model "levels" are:
GX/GL Sport - 2.0 4 wheeldrive
WRX - 2.0 turbo
WRX STI - 2.0 turbo

 

right ok then its Parkers thats confusing me as they have the Impreza estate listed as both the WRX and the WRX Turbo
see here --- http://www.parkers.co.uk/cars/specs/...aspx?model=849

 

It was just how they were marketed in the UK iirc...
The differences are simply manufactured date: Pre and Post 2003
