I agree that the car temperature will always show as 3-5 degrees C higher than it is when it's been sitting in the sun, so the temperature would have been more like 28-29C when you took that photo @BigJanette
It's 31C here right now (West Mids) but I guarantee if I go and switch the ignition on, on the car now, it will be 34-35C.
It was 4 days ago (when you posted the picture.) It's probably is in the mid 30s now!
