Nice step-up from a Saxo VTR! I went from Punto GT to my 182 over 9 years ago and I definitely noticed the improvement. You'll be doubling your power I would have thought?
As Chi says - make sure the belts have been done or factor-in some money if they need doing. Birchdown in Malpas is definitely worth the 50+ mile trek, dependant on whereabouts you are in Manchester.
