We picked up a used Mahindra a couple of years ago and I went through a local bank and got a 4.75% rate. I am a small-time farmer, and the tractor is used on our farm. We checked some other local options, and they ranged from the aforementioned 4.75% up to about 11.00%, so it pays to shop around.
We have used unsecured personal loans in the past to purchase equipment, and the rates were usually about 5% or so.
One of the more interesting ways that we financed was through our local bank. When I bought my dozer, we had cash to buy it, but didn't really want to end up "cash poor". Our local bank offered the option of using the money in our account as the collateral for the loan instead of the dozer (so they had zero liability). We did a loan at about 3% interest, and the bank only took 1% and the other 2% went into our account as we paid the loan off. (This sounds more confusing than it really is). What it was, more or less, was a structured way to make sure that I would "pay myself back" for using my own money, and the bank, more or less, got a percent to facilitate it.
Good luck and take care.
