How many sheep and men can fit in a small car?

Police in New Zealand did a traffic stop on a suspicious vehicle.  The small car contained 10 sheep and 4 men.  It's a very hot day and that many in a car will create a lot of body heat especially when most of them are dressed in wool.  It was discovered that the sheep were stolen from a nearby farm.  They were returned unharmed but a bit shaken.  The men were arrested.  10 sheep and 4 men
Update:  11 sheep
