MCI 96A3, MC 102A3
The 102A3 was the first production 102-inch MCI bus available to all buyers (first delivery in October 1985) and quickly became more popular than the older, 96-inch width. Only the passenger section of the buses was widened; the front assembly with the windshield is still 96-inches wide and the body widens at a 5.5-degree angle alongside the driver.
