S3 road tax for 2008/2009 which is currently in band F 217g/km will be £210. When the new system comes into play in 2009/2010 it will be in band K and cost £300. However if you were to buy a new one at that time you would have to pay £550 for the first year, the so called "showroom tax", and then £310 per year in year 2 and subsequent years. (But we all know it will have gone up further by then!) http://news.bbc.co.uk/1/hi/in_depth/629/629/7293011.stm Or do I have that all wrong?
