380N Cars: provisions as to hire-purchase, etc.
(1) In the case of a vehicle to which this Part applies, subsections (2) to (4) shall apply.
(2) Where a person, having incurred capital expenditure on the provision of a vehicle to which this Part applies under a contract providing that such person shall or may become the owner of the vehicle on the performance of the contract, ceases to be entitled to the benefit of the contract without becoming the owner of the vehicle, then that expenditure shall, in so far as it relates to the vehicle, be disregarded for the purposes of Chapter 2 of Part 9 and in determining what amount (if any) is allowable as mentioned in section 375.
(3) Where subsection (2) applies, all payments made under the contract shall be treated for tax purposes (including in particular for the purposes of section 380M) as expenditure incurred on the hiring of the vehicle otherwise than by means of hire-purchase.
(4) Where the person providing the vehicle takes it under a hire-purchase contract, then, in apportioning the payments under the contract between capital expenditure incurred on the provision of the vehicle and other expenditure, so much of those payments shall be treated as such capital expenditure as is equal to the price which would be chargeable, at the time the contract is entered into, to the person providing the vehicle if that person were acquiring it on a sale outright.
