The little Citoren c2 vts hdi's are pretty impressive 65mpg 110hp £30 road tax & after a remap wont hang around thats what i keep looking at although i do like the comfort of my A4 tdi but really hate waisting / giving money to the goverment & want the best mpg possible with the cost of fuel continuing to rise but still need alittle bit of performance so they dont seem a bad option...
