Took it for a spin at the weekend Fabulous!!!!!!
4 or 5 mpg less than before - but wow - (I was playing with my new toy!!!!!!)- those who have done the conversion will know what its like - if you have to ask - you wont understand.
However - going into work this morning I was stuck in grid lock - journey took 50% longer than usual - the stop - start - crawl (repeat ad nauseum) threw up no nasty surprises - maybe its rose tinted specs but it actually seemed smoother if anything.
