I cannot remember the time limit, but if anyone is contemplating a coach purchase on an older shell but as a new coach check the Detroit
Diesel warranty. Detroit starts the warranty period after a certain time expires, not when it was put in service. We have seen coaches that had four year old chassis (the only date Prevost goes by is their model year regardless of the title year) being sold as new with titles in the current year, and engine build dates five years old. Clearly those coaches when sold may end up having very upset owners who will not get the warranty coverage they expected.
