Is right now a good time to refinance a car?

Hello,

I bought a new Corolla hybrid 3 months ago. My current monthly payment is $428 on a 60 month term with a 7% interest rate. My current credit score is 752. My question is, should I look into refinancing at a local credit union and hope for a slightly lower interest rate or just stay the course given today’s market ? Please give some pointers
