Let well maintained old cars remain on the roads

Do we want to wipe out  years of heritage from our roads by banning cars older than 15 years from our roads. Lately there has been discussions to ban all vehicles older than 15 years from plying on Indian roads because they add to pollution levels in the city. Although it has been proven that pollution from traffic has a very small contribution to the overall pollution level, why don't we, instead, enforce more stringent pollution control measures no matter what the age of the car, rather than wiping out absolutely fine old beauties and   heritage from Indian roads. Let us encourage sustainable consumption and care for our products rather than just going by newness.
