KOBRA Wireless Car Scanner
It's hard to trust your mechanic after having been recommended a 50th air filter replacement in one year's time. (That or you should stop chain-smoking tree-trunk-sized cigars into the air vent.) Either way, the KOBRA Wireless Scanner watches for manufacturer trouble codes and beams them directly to your phone, so you can diagnose problems as they arise. No, not all mechanics are swindlers, but now you can at least weed out the ones who are. Grab one of them here for $16.99.
