we cannot compare the Volvo B7RLE and Tata's Marcopolo in Chennai. I think the Marcopolo's can compete with the Ashok leyland buses. They are absolutely low on power and the noise was also more. There is a huge craze for Volvos in Chennai and cities around chennai. I travelled in a B7RLE to Vellore and came back in another B7RLE. The travel was sooo smooth. The Volvo overtook all the govt and private buses which came their way. On my return i reached chennai koyambedu bus stand in exactly 2 hours.
