"I need to take my car in for inspection."
".the problem is recently the check engine sign popped up.which sucked because i just invested around 800$ in repairs and a wreck i had pryer"
I don't know what kind of car you have, but as far as car repairs go $800 isn't terrible. And if you were able to go to a body shop and get out for less than a grand, you're doing very well.
" what auto zone told me its a problem with the exaust n while the car is driveable."
Probably an O2 sensor or catalytic converter efficiency not being what it should be.
".i cant pass inspection now..without whippin out another 500 on repairs.."
Okay. Did you get a 2nd opinion and/or quote?
"If i was too use another vehicle for just the inspection is there a chance i can use that paper work at thr place u get registration stickers for my own car.. "
LOL, do you really think that they haven't thought of that? When the car is taken in for inspection, it's VIN , make, model, mileage, color, and plate are all noted. If the car passes inspection the sticker number is matched with the VIN. Even if you scraped off the inspection sticker and put it on your car, you would be found out and charged with fraud and fined more than $500. Stupid idea.
