Loan for a car without interest

I am looking at purchasing a brand new car from a dealer.
Are there any methods of borrowing 45k without having to ‘pay interest’ whilst not having large monthly payments as well?

Ideally want a plan that works out no more than £550 a month over 7/8 years.

Have a look here for an article from IFG around car leasing:
