22: Toyota MasterAce Ice Maker
The Toyota MasterAce is one of the most iconic minivans of the 1980s. Toyota had a great run building these vans originally, and there were some unique features. The MasterAce was a great car if you wanted the recreation of an RV, but the compact demeanors of a minivan. Prior to the redesign in the 1990s, the MasterAce had many unique features (via CarBuzz).
The built-in ice maker was one of the most popular features of the time. The van could make ice on the fly, and it made the perfect companion for camping and outdoor activities. Why stop for a bag of ice when you can just get it fresh inside your van? Definitely a unique feature that made the MasterAce a cool van.
