If you are interested in buying a bus for transporting passengers, then you are most likely interested in having it for one of two purposes. Either you wish to use it for business, or you are looking to purchase a school bus. Buying a bus for any purpose is a heavy investment, so you are going to want to minimize the time you spend finding one. Additionally, you are going to want to ensure that you get a fair price and that it suits your needs.If you wish to purchase a bus for a school, you are most likely going to want to look for one of several manufacturers: Thomas, Dina, Bluebird, or International. There are a few other manufacturers that cater to the school system but theses are some of the most significant. Ford is a good company to look for if you are interested in a smaller coach. By starting your search here with these companies, you will find that classic yellow bus you are looking for.If you wish to purchase a passenger bus, then the next factor is what size bus you want. Ford tends to dominate the market in small coaches whether its for school or passengers, so again that is the place to look. For larger vehicles, MCI, Neoplan, Prevost, and Vanhool are three good companies to start with. MCI is by far the most common one to go with. They put out quality coaches at a fair price. Vanhool, Prevost and Neoplan aim for higher quality but obviously at a higher price.Armed with your new knowledge on where to start looking, it is time to look! First and foremost you are going to want to gauge how long you want the coach to last. A well maintained diesel engine will last a million miles, so with that in mind, the five hundred thousand mile mark is a good break point. Over that means you are looking to save the most money. Under that means you are looking to get the most distance. If you choose to go for a coach with more miles on it, take a close look at the engine as well as the interior and exterior. If there is noticeable wear on or in any of these areas, it suggests a coach that has not been well maintained.At this point you are fairly well educated on the bus in question. Of course you will want a Carfax report to find out the vehicles history. You should also look for similar offers to make sure you get a fair price. Transportation fees can often be nominal for such a potentially expensive vehicle, so if you can save a couple thousand dollars getting a bus 500 miles away, the cost to get it will be well worth it!
