out of your list id go with the impreza or the s3
hondas too frantic and not quite quick enough for my liking
golf r dont know much about but doesnt seem special enough for the price tag
focus, nice car but suspensions rock hard, fuel economys down with saloon impreza sti's and theyre getting a bit too common lol
evo, very hardcore for an everyday drive
s3 has probably the nicest interior,fuel consumption on a par with the others bar the civic,4wd which is nice to have
current sti has best interior so far,and with a few tweaks will outpace all but the evo easily
for fuel on all of them your going to be mid 20s to low 30s and servicing will probably be pretty similar to what your already at - they are performance cars after all, you pay to play!
