Info from Licensor: "I cooked 1,5 kg pork roast inside an old Datsun Sunny for 10 hrs on a 39-degree celcius day. It worked a treat. A few things to note. It has tinted windows ,door & window seals are shot & there is a big rust hole in the roof, which stops the car getting as hot as it potentially could. If this was a later model vehicle & painted black the temperature at a guess could climb significantly higher."
