Break Down Lane by CarTalk makes it easy to find a mechanic when you find yourself in a new city and car starts acting funny. Purchase the app for $1.99 in the iTunes store, and never be forced to call an expensive tow truck again.
This app will pull up a map of your location with all of the closest mechanic shops. Each location has a short summary of the shop and the ability to call within the app.
As an added bonus, the app has roadside tips, including how to properly change a tire.
