Vintage Capsela Toy Store Shop Display Electronic Eighties IQ Builders Set 400

Capsela toy shop display I think from the 1980’s. The back wheel section of the crazy car has disconnected from main body. Would probably be possible to open case to reattach but I haven’t tried. I used a multi power plug to test and motor in back wheels spun but as separated from rest of car it didn’t move cogs in rest of vehicle . Please see photos
