Installation is just a plug away no messy wiring to deal with. Size is small and compact not bulky like other gauges, no need for other gauges anyways you have a multifunctional gauge all in one. Price of the ScanGauge is affordable at $170 or even cheaper with coupons from the site. I recommend the ScanGauge OBD II. It takes only seconds to install, and can save you a lot of money either through gas savings, checking trouble codes, or spotting potential problems before they turn serious. This is a must-have for the car enthusiasts. I originally bought them just for the voltage since my car didn't come with one. The gas savings is just an added benefit and soon the gauges will pay for themselves with gas on the rise again.
