Thnks! Right!! All makes sense now - MY is Model Year (of course, shoulda seen that). I was going to try and do a lesson in this from searching the net.
Just checked and was wrong about Oct build - it's actually Sept 08 and the model is given as VE8EP35. Can't see any MY at all on there. So the MY designations might have come out just after that maybe..., if Sept is the start of the model year then when I get parts from AMCAP here in Perth and give the VIN, it decodes as 09 - so that's maybe why.
Anyway, just to cram everything into this post... I just rang that guy on ebay who I posted the pics of the rims. He sounds honest over the phone and those two are fronts (8.5" x 19) with almost new Pirellis and he also has a set of new rears (9" x 19) for the S2 VE Redline, in boxes (no tyres of course) . I'm buying the set of 4 and working out a price soon. So, very happy if it all goes through. Can't imagine 275 (or similar) Pirelli's will be cheap though! But I don't have to get the same brand on the back, although it would be nice...
Appreciate everyone's help on this.
