i doubt you'll get the colour you want. At the end of the day you get the car thats up to standard and in good cond, not what it looks like. Esp with k11's being a bit crap on the sill side.
I realise you are only 18 Jinata, but does it really make that much difference on insurance between the 1 litre and the 1.3 ? there's only 1 or 2 groups difference, click the link for groupings. http://www.parkers.co.uk/insurance/Groups/by-model.aspx?model=608
