In 1973 the chrome bumpers were removed to make way for the new sturdy all aluminum bumpers along with the side lights replacing the reflectors. These two changes were the last major changes of body style that Checker made.

When the 1974 model year was over, the eight-door Aerobus was discontinued. It was reintroduced in 1977 in a different configuration. It was an eight-door stretch of the A11E Taxi with room for 15 passengers. That too was short lived with the last one rolling off the assembly line at the end of that model year. Again, Checker was back to four models, never again to introduce another new one.

After the recession that started in 1979 and lagging sales, coupled with a change in the taxi industry, and ever imposing new government regulations, Checker closed the doors on the sixty-year-old assembly line. The Checker Cab was considered the Rolls Royce of the taxis in it's hey day. It was a sad day on July 12, 1982 when that last iron horse rolled off the assembly line in Kalamazoo, bearing the green and ivory colors of Checker Taxi of Chicago. Sixty years prior to this, the first cab bearing the same color scheme, rolled off the same assembly line and onto the streets of the big cities, proudly carrying it's passengers to their destination. It will not be long though before the cumbersome cab with all that room inside will be nothing but a fond memory to many people as they squeeze into the little compact with their suitcase on their lap reminiscing about the good ole' days.

The company in still in existence, expanding it's outside contract work, mainly in the sheet metal stamping and sub-assembly work for the automobile industry.
