New focus st is a face lift version of the current one so emissions is the same the new civic is estimated at 181 g/co2 so that puts it at 750 a year same as the astra, also the new civic is estimated to be 26,000 gbp which would be 30,000 odd euro and vrt at 30% based on co2 plus vat I'd say it will be in the 40,000 area so still expensive compared to the focus
