It's a good business selling surplus cars. You need a sufficient capital of this but you can do this without a capital. First, your location must be beside or near the national highway so easy for the people to see your car displays. As soon as you're credible to do this business , go to car sellers and make an agreement to sell their surplus cars and provide you only the consignment or commission. You ask the main car seller if you can use their petmit to sell.
