Well, not Cheat the man so much as help you DIY types do repairs on your modern, computer-assisted cars without going down to the mechanic and paying an arm and a leg to find out what's going on. The product in question is the KT600 Diagnostic System, made by Kingtec Instruments. Plug it into your car's computer via the OBDII connector and it outputs to the unit's 6.4 inch LCD screen, where it will give you diagnostic information about your car's current status. Of course, just because you know what's wrong doesn't mean you can fix it...
