2004 Hyundai Tiburon Emission Failure Question?

I found a Tiburon being sold by a dealer in Ga. Good price with good mileage. I looked at the carfax report which they have for free here is what i found. It got into car accident at 4,000 miles but it got repaired by Hyundai and certified. It also has a paper trail and carfax trail on maintenance, emission test which it did pass then all of a sudden its reported that after the car was sold to the dealership they couldn't pass the emission test on it which was 2,000miles in a year of a difference from one owner to dealer. The dealer tried 4 times to pass the test but all those times it failed. Im in Warner Robins Ga and believe it or not here it is not required to get your emission on your car. Here is a more in def report of what the car has been thru….

If someone with mechanical knowledge give me some inside advice. Stay away or if its a easy fix.
I have been told from some friends you have to drive a car 90 miles for the computer to reset its self on most new cars after the battery dies for some time. Is that true? Could you list a list of things that could be wrong with a estimate amount of money that it would cost to fix it? Would you even buy it? Email me at marlene.t.vang@gmail.com if any questions in order to answer my questions if possible could you give me some kind of contact like a email in case i have further questions

THANKS!

Sometimes a car can be a lemon right off the lot… sometimes it takes a while. Whether or not the state requires emissions testing is irrelevent. If the car has low miles and the dealer can't even get it to pass emissions, then the car must ot be worth the time, effort, ot money to repair it properly. The dealer is probably trying to just get rid of the "great deal" they thought they had when they purchased the car initially.

Without even asking one question, I can tell you if you intend on keeping this car for any long period of time and you need reliable transportation, pass. Go out and find something else. There are a lot of deals out there. Don't settle on this.
