Deferred student loan; Good idea?

I'm looking to get a deferred student loan for $6,500, which I won't have to make repayments on until I've graduated and in a full time job. It'll be my first time going into debt, and I plan on buying a car and a high-end computer for university. My dad is incredibly skeptical about this. I've talked to a financial advisor, and he said it's a good deal. I can defer the loan up to 5 years, and pay it back in 3 after I graduate and have a full-time job.
