I like that many were made into little diners. See the inside of one at the Henry Ford museum https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhQmqovvvByGlSqFywZsjsfK0KQeJEHiwV5kG1BELG74gZD6rRP8n0gpwjY9D-OE_P8YqyB8_SiZ-W5K-hahVKv_TlIMfCLkmYdfFbAea1JyGb9wjUqm6qZq1RXX0ur6DosazQZVhpYFow/s1600/Henry%2520Ford%2520Diner%5B1%5D.jpg it is the nicest I've seen, most are far more simple and less ornamental
Some were made into houses: http://justacarguy.blogspot.com/2009/09/street-cars-getting-second-life-as-home.html
And in San Diego I found one diner street car, and two homes made from street cars http://justacarguy.blogspot.com/2008/06/survivors-of-era-i-doubt-anyone-else.html
