I am currently looking at PX ing the M2 for an RS3. I have only two option here in Ireland. Anyway I will cut to the chase, one of the cars has been spec'd with the upgraded 192 alloys, the one with the wider 255/30/19 tires on the front. So according to the Log Book, this car's CO2 emissions is 191 grams vs 189 on the regular 19". In Ireland our road tax is based on these emissions, 171 to 190 = 750 euro per year and 191 to 225 = 1,200 euro per year. The road tax IS based on the V5 log book (or Irish equivalent) can anyone with the upgraded 19" x 8.5J front alloys confirm from their V5 what the emissions are in the UK please?
