The largest collection of model ambulances is 10,648 ambulances and belongs to Siegfried Weinert and Susanne Ottendorfer (both Austria), in Wiener Neudorf, Austria, on 7 April 2012. The husband and wife team began collecting ambulances by competing against each other to see who could get the most, before combining their collection to set the record. Their basement houses three rooms filled with model ambulances, one filled with ambulances from North America, a second with ambulances from South America and Asia and a third housing European ambulances. The oldest ambulance in the collection dates back to 1895.
