Truck Parts

I was interested in mercedes truck parts mainly actros and axor and scania too.
I wanted to know if you can give goods on credit, for instance you give me a 20/40 foot container and we agree on the terms if I can pay monthly whatever the price we agree on.
I have seen 3 companies who are based in Germany and have a branch here in Nairobi who do the credit thing, so i wanted to hear from you too.
