Atlanta
I have a GN as my daily driver in Decatur. You do have to have it tested. Mine is dead stock and I think I've had it done twice once when I initially bought it and one more time after that and it's done fine both times.
Loganville is- I don't know about 45 minutes from Decatur with no traffic? Depends on what you're driving too, sometimes I make it out there in 30 :biggrin: BUT. this is Atlanta, I dare say you're looking at an hour and a half, hour and a quarter with traffic because the VA hospital is close to Emory and every single other person in Gwinnett comes down 78 to go to that area in the mornings and back out in the evenings.
You NEED, MUST, ABSOLUTELY, BE SURE you have several LAYERS of security on your car in Atlanta.
