Yeah, that's the problem. It's going to be what, £20K for one of these? The outgoing ST is a better car in a lot of ways and you can get them for a third of that now.
And if you must spend £20K, there's the outgoing RS to fill that slot. Quite why you'd have this over a Mk.2 RS I really don't know, there's the fuel economy argument but then it's a hot hatch?
They'll most likely be a great buy when they've lost a bit of their value.
