I own a st24 and a series 2. If you want comfort and a gas guzzler then the st is the choice. If you want a fastish car that will make you smile from ear to ear then the series 2 is the choice. The feel in speed is totaly different. The fuel is better on the series 2 but you dont worry about fuel costs on a high powered car any way. The way things are going the mondeos will be worth nothing but a few hundred quid in a few years thge way the tax and fuel go up.
