For anyone not wanting to get screwed by their local auto mechanics shop, DATZOO offers their FixDat personal diagnostics tool. You just hook the device up to your vehicle when you suspect something has gone awry, and it will run a complete diagnostic test on your car to tell you exactly what the deal is. You can then bring your car in for fixing with full knowledge of exactly what’s wrong to make sure it gets fixed, and not broken further. We even get a bonus proof of concept at the end, although it was told by a DATZOO representative, so, you know, grain of salt?
