I dont think the new model will have a significantly lower CO2, current model has 167g or something and to make savings would need to get under 155g, which I can't see happening, due to size of car and weight, and also in the UK road tax for this car is only 170 so no big saving to be made in teh UK market and Ireland too small. Not sure about other markets.
If this car sells for 32k, the it is made up as follows:
Pre Vat (21.5%) 26.33k
pre VRT (24%) 21.24k
now with lower CO2 band (20%) car would cost
Base Cost of car 21.24
+ VRT (20%) 25.48
+ Vat (21.5%) 30.96
so difference is just over 1k, you would have reduced road tax from 430 - 290 or something, but I don't think they are going to make significant reductions in teh CO2 to get to lower band.
Have a look at the UK where you can get a 2008 2.2D for just over 17k euro all in, I am buying petrol 1.8T3 for 18k, know Diesel will be cheaper aslower VRT 24% as opposed to 28% for the petrol (178g), but smaller engine so insurance lower, and should benefit from tax based on CC rather than CO2 since registered in the UK pre July 2008.
but Diesel's May 2008 can be had for less than 11k sterling and VRT is between 5.3k (2.2Dt2) - 6.6k for (2.2D SR)
