Eventually got this to work.
If you choose the options "carefully" - the cost can be reasonable (in terms of overall cost).
I went mad first time I did this and reached £108k
Second time £82k
People say Audi/Merc and BMW - have expensive options.....Morgan are also pretty good at this tact!!
Is one new PlusSix worth £30k more (due to options being ticked) than another....the answer is of course no.
