Is my wine still good?

I have way too many things in the trunk of my car—things I haven’t disturbed in a year. I recently discovered a bottle of wine buried in my trunk. It’s been there for about a year. No judgement please. LOL!

We have all four seasons where I live. This $15.00 bottle of wine, that was supposed to be a present, has been in my trunk during freezing cold and parching heat. Is this thing safe to drink?
