simple fact of the matter is that the 2 litre non turbo is easier to run ,
1.6 is an animal on juice , have an extremely heavy body to lug around coupled to a awd system its not the most economical impreza ever ,
I had a 2005 1.6 ts and nearly cried with the fact that my mate was getting further to a tank of juice out of a v5 sti , i bought the 2.0 sport in 2007 and honestly costs less to run , im blue in the face telling people the same story once they say there thinking of buying 1.6 ,
Very little in the difference to tax or insure but the better mpg wise and you get a bit of poke compared to 1.6
