I always thought that grunt wise the 200tdi was the best, then the 300tdi which traded off grunt for better/smoother driving and higher top speed then the Td5 which was even more road minded coz of its bmw heritage???^^^^What he said. For what it's worth, I've had 200 & 300 Tdi's and currently own a Td5 which is my daily drive and green laner (as were the previous Tdi's). Personally, as much as I liked both the Tdi's, I'd take a Td5 every time. The Tdi's I think were slightly more economical but the Td5 has more grunt. Try both out and see what suits you best.
