This has been bothering me for awhile, but I have been told although by a source with questionable reliabilty, that WRXs along with all fulltime AWD cars are exempt from E-Checks in Ohio because they don't have the right dynos for them to roll on. Now, it has been several years since I got an E-Check, but I do seem to remember that at least at the center where I got mine, they did one have one dyno, which would be incompatible with our cars. Furthermore, it does say in the WRX owner's manual that because of this there are certain areas of the country where Subarus are exempt. Does anyone have a definite answer to this? I live in Geauga County.
