I am starting to see quite a few older XLII buses out there with the new round style headlight conversions. I have talked to Prevost in Nashville, Parliament in Clearwater, and Excaliber in Sanford. Prices are ranging from $4,500 to $19,000. Obviously the lower end of that range makes this upgrade an attractive option whereas the upper end does not make sense to me anyway. Has anyone out there had this done to their coach or seen one up close that has?
