I require some help from the forum to finding me a suitable bus from Chennai to Coimbatore. There are few things which are would like when choosing the bus and bus service. I would like to bus preferably to be a Volvo bus but not necessary, as long as it should be an AC bus. I would like the travel on a bus which is comfortable, as the journey would be long. I need to know where to depart the bus from in Chennai and where it would arrive in Coimbatore.
