Recovering VAT charged on repairs to a car

I have a question regarding this ruling:

5.1 Recovering VAT charged on repairs and maintenance If you use a vehicle for business purposes, you can reclaim the VAT you were charged on repairs and maintenance as input tax as long as the business paid for the work. It does not matter if the vehicle is used for private motoring or if you have chosen not to reclaim VAT on road fuel.

If I pay for a service with my business account ( in order to claim the VAT back) how would I show this in clearbooks? It obviously isn't a business expense to service your car so not sure how to explain it. I'm a sole trader and do about 5000 mles a year for work.
