I worked at the Willow Run Assembly plant in Ypsilanti, Michigan that built most of the X-Cars and we knew from the jump they were not built to last, I did have fun trying to smoke the tires as we placed them outside for shipping, but after building all those SS 396 Novas and driving them over the years there was really NO comparison! I saw a Citation in Chicago last summer and it was the first X-car I can remember seeing in many, many, years. When GM closed our plant there were first run-never driven cars for every model we built there at Willow Run starting with the Corvair, Novas (and the Pontiac & Oldsmobile offshoots) then the Olds Delta 88, the Pontiac SSE’s and finally, the car that killed our plant, the horribly ugly Chevrolet Caprice. I don’t know where all those pristine cars ended up but would like to have a few of them now! On the Novas I worked on the stub frame front end and can still close my eyes and assemble the front hubs, control arms, springs and shocks in my head. After all, we did built over 200,000 a couple of years running!
