Question about interest deduction for New Vehicle Purchase

I purchased a used car from a private party seller.

I borrowed $10,000 from a friend to make the car purchase, under the agreement, I would repay him $12,000.  Those debts are resolved.  Is the $2000 in interest paid on the $10,000 loan deductible / claimable or does such a deduction only apply to loans furnished by a licensed lender or finance company?
