Unfortunately the locals are choked everyday by these dangerous vehicles. They are way beyond their use by date and the residents of Malta deserve a modern, efficient and clean form of public transport. If a few tourists won't come back because of a few old buses that let that be the case because there a many, many more things to see and experience in Malta. However, the health of the people who live in Malta day in day out must take priority.
Most of the current buses if not all are breaking the EU emissions regulations by many times. The regulations are there for a reason. A few of the best and maintained old buses will be renovated and used on certain routes at certain times of the year - a bit like some of the old Route Masters in London. The rest will be Euro III minimum standard with Euro IV a year later.
Malta's transport system cannot remain living in the past because at the moment the buses are so badly maintained, polluting, unreliable and to be honest quite rude to many tourists that change had to happen. Too many cars are present on the island so a new integrated transport system has been a long time coming and hopefully it will ween a decent number out of their cars.
With the new tariffs from next year with the incoming system, Malta will still be by far the cheapest public transport system in Europe with air condition, clean and quiet buses becoming the norm, just as you would expect in any decent modern European country.
You have to remember that Malta isn't a Museum, it's a living county with people who need to commute to and from work and live/breath in un-polluted air.
