Vintage 1971 Kenner Smash Up Derby game

Box has wear. Not complete, but Includes 2 cars with all the parts that are supposed to fly off; 2 ramps; 2 “T-handle power sticks” to make the cars go. Blue car is missing one wheel but to play the game the cars actually only sit on the large spinning wheel on the bottom. Both cars work well this way and the T-stick makes these large undercar wheeels spin well. The white triggers on the front of both cars press in and make the odd coloured parts fly off. Some amazing nostalgia here for us 70s kids. I totally remember these commercials during my Saturday morning cartoons!!
