Is this worth it?

I need a pickup truck for 2-3 years of headache free and and I don’t want to get on a payment with interest and all of that bs. After three years I’m planning of buying my dream pickup truck in cash.

Is this a good option? This would be my first ever truck. The sellers are an elderly-ish couple who had a gardening business and are now retiring.

I’m planning of going for a test drive tomorrow. What are some things I should consider?
