Do you think the milk I bought is still safe?!
why don't you try juuuust a little.
and if its still good, then drink it :)
only way to know ; )
If your car was left outside in the sunlight the temperature inside was likely high enough to spoil the milk. There's no reason to risk illness. So, you should buy new milk.
drink it and if you get Montezuma's revenge, then you know it has gone sour, otherwise you keep on living!
It's not like you'll get food poisoning from tasting it ...
