User Capt_Nitro's 1988 Cavalier z24 had no cup holders. The captain cut off the front of the ashtray, made a piece of wood to fit, and cut two holes big enough to fit a soda can. The cup has to be removed when parking, because the cup holder is too close to the shifter.
"Inside one of the trucks for the company I work for. Apparently it was supposed to be an automatic, but at the last minute, Dodge decided to make it a manual. Whoops, they forgot about the cupholders!"
