In these days new models/designs of mobiles,cars, furniture coming and people want to sell older goods and same time other want to buy used good condition products but from reliable source. People hesitate to buy specially used goods (car, mobile phone, any ) but they love to buy from someone they know directly or from friend's reference. Idea is to buy/sell , get info about used/almost new items in your circle of trust using facebook, linkedIn etc, You will get notified once someone in your circle want to sell something (car,bike,mobile phone, etc). You can explore public ads as well and it will help to navigate to connection chain to that person like LinkedIn. You can inquire something if you want to buy in your circle.
