Thats whats great about GA....no inspections, no rust.
Nah, it gives you peace of mind to have an official inspection place tell you your car is in good enough condition to drive on the road. If they found something that needed fixing, like a real CEL (mine seems to be a computer glitch, says they've checked it over 20 times in the past 8 years, scanner never said anything), the brakes needing attention, or an issue with rust, it forces you to take action to fix the problem or get pulled over by a cop.
Now inspections can get annoying when you have a car in excellent condition, like my X90, because you know it'll pass and spending $12 on a sticker seems pointless. But for my Civic, I'm kinda glad it has to pass one.
