I'll have to get one if I ever buy a Prius or a Tesla

[boxxster]

Haven't used that one but I have used Revheadz (free app that works with a bluetooth OBD2). Haven't used it on the boxster but did try it on my daily. Actually works really well. Definitely worth it for the laughs if you already have a bluetooth OBD2 adapter.
