Valuing A Car Question (Time Value Of Money?)?

I've got a homework question for Finance that I'm struggling with and I was wondering if anyone could help me.

The question is:

"J has just bought himself a new car. He made an initial deposit of £1000. He will make 36 monthly payments of £200 each. The dealer charges 12% APR on credit sales. What is the price of the car?"

I somehow keep coming up with an answer of £5836 but I don't think that's right. Can someone please explain this to me?

    Assuming the payments are made at the end of each month, the present value of the annuity (loan) payments is given by

    PV = Pmt x (1 - 1 / (1 + i)^n) / i

    i = 12%/12 = 1% per month

    PV = 200 x (1 - 1 / (1 + 1%)^36) / 1% = 6,021.50

    The deposit needs to be added to this, so car price = 6,021.50 + 1000.00= 7,021.50
