What are the best car-related apps out there?

To find out, we turned to you, our loyal Car Talk visitors!

Here’s a sampling of your favorites, compiled by Car Talk staff in a semi-pseudo-scientific way. We hope this rundown is helpful.

Have you used one of these apps? Let us know what you think. Know one in the same category that does the same thing, only better, in your humble opinion? We want to hear about that one, too.

Share your suggestions in the comments section for each app, or in our humungous, on-going app discussion, below.

Thanks!
