Phase 1's like mine (a 2005 ST) can be had for about £8,000 or phase 2's with average mileage or maybe even lower for around £9,000 - £9,500. The Archers of Ashby deal is fantastic too. You could also go through one of the online companies like
http://www.allbrandsnew.co.uk/ or
http://www.coast2coastcars.co.uk/ and they come in more or less the same price as Archers do.
