A 1959 Eureka Cadillac 54" Hi-Top Ambulance is the vehicle Homer buys in Diatribe of a Mad Housewife. It looks like it is in good condition but Boris claimed that it is really worn-out with only the siren working, though Homer still buys it, as he heard the siren scream "BUY ME".
It later was crashed into the sea and became a fish habitat.
