My car doesn't have a/c

It gets hot in my car. Somehow I didn't think to look to see if it came with a/c when I bought and now I live with out it. It's just the way it is. Honestly, I didn't realize that there were new cars that were made without a/c. Who knew? I just feel bad for my friends and coworkers who have to suffer thru it but they have all been nice.
