I am looking at buying an OBD2 scanner for my Fisker. I was looking at different ones made by Innova. There is a wide price range for these scanners. I don't want to go too cheap then have to buy another one when I realize there is some feature that it doesn't have. The problem is I have never used one, so I don't know which features I need and which ones I don't need. Any recommendations from Fisker owners that have used a scanner? Innova doesn't list Fisker as one of their supported vehicles.
