My sons share a 2006 Camry. It is in good shape, but they aren't great about keeping up on regular maintenence. When a check engine light comes on, I see dollar signs! With this tool, you just download the app on your phone and plug the device in your car. It will tell you things about your car's condition that you didn't even know mattered!

This would be a perfect gift for anyone who has a car and a smart phone! #Rankboosterreview #sponsored #OBDII
