I understand......In Nashville two hours away they have yearly emissions testing.......Here in Knoxville we do not........100's of cars on the road here would not be in Nashville due to the costly repairs it sometimes takes just to pass emissions.......When I had my salvage company in Nashville we had one truck that worked great but every year we had to drop $300 to $500 to get it to pass........The engine light would stay off for a month or two then right back on it came and would run fine the rest of the year.........GO FIGURE
