No the description is correct because at each stage its paid on the value added by the person doing the transaction. I agree the amount is about the same but traders would like people to believe the myth that the reduction is due to vat when in reality its due to the mark up they need to make to trade. The value of anything is what someone will pay for it.
I would like to see evidence that the supplying dealer has somehow added value to the new MH.
PDI? - A tick sheet exercise that misses defects. The first owner ends up having to make warranty claims. What else? A wash and polish. A handover. Nothing remotely close to adding any real value.
[The "extras" that are dealer options have their own VAT element so don't count.]
