The last time I had my honda with tinted windows inspected here in NC, they charged an extra $10. Something about having to use a special tester to check how dark the tint was. Not sure if thats a state charge or just from that jiffy lube place.
Also, this was the same time I had to replace the drivers side wiper...so it ended up costing me over $50 for an inspection. Luckily our local mechanic just became a state inspection place so I can start taking it to him.
