donor receipt

[HandyAndy]

cheers for your comments,
the reason i asked such a basic question was whether i would need to prove the date i purchased my donor to the iva within my builder folder etc like my receipts for steel for chassis etc.
yes i,ll be putting the V5 into my name asap & will use the car till end of april as it has tax & test till then, and then i,ll sorn it,
i,ve also booked the car in with my local friendly mot station( where my current vehicle is tested for last 3 years) for an emissions test (£10) just to give me an idea of state of the engine prior to stripping out of the donor.
cheers
andy
