Business must be booming for Triple-A.  Because we're all pretty helpless at this point if our car breaks down.

A new survey found 68% of cars currently have at least one thing wrong with them.  And when people were asked whether they could handle relatively simple fixes . . . like changing a tire . . . the answer for most was a resounding nope.

Here are six fixes, and how many of us feel "extremely confident" we could do them . . .

Could you add windshield washer fluid to your car?  30% aren't sure they could.

Could you replace your windshield wipers?  52% don't know if they could handle it.

Could you jump start your car if the battery died?  53% don't know if they could.

Could you put a spare tire on?  61% aren't sure.  One in five don't even know how to use a gauge to check the tire pressure.

Could you replace a blown fuse?  63% aren't sure they could do it.

Could you change your own oil?  67% said no.

Now here's the craziest stat.  Researchers showed people different photos of car parts.  And 41% couldn't even identify which part was the engine. WOW!!!!
