While I wait for my EV1 (maybe a long wait) I still have to get around. My brief foray into dual fuel petrol/LPG was not successful for me; I do too many short journeys and the car took too long to click over onto LPG; I need a car that can go at motorway speeds (that rules out the GeeWhiz)... So I came up with PLAN B. We already have a small Vauxhall Astra... so what should we have for a second car that I can use for my short trips and commuting? I've always wanted one. And now I have one! A Smart Roadster! Fun, economical and fun (did I mention "fun"?) 700cc engine built by Mercedes; 55mpg: its almost a pleasure filling up! And while the car is no longer being made, I guess it wasn't economic for Smart, I highly recommend.
