Buying from New Jersey. Should I be worried about flood?

[Moussa93]

Hi there,
I have been here for some time doing a lot of search and it looks like I finally found the Z I was waiting for.
2011, White, Sports Package with only 11k Miles on it.
Price is totally fine, too, as the dealer has been trying to sell it for 6 weeks and just lowered it $2.5k
I am ready to pull the trigger on it but I have been told that I should I look at Zs with a flood title. Carfax is clean, I checked on New Jersey's website and the Vin # is not listed there.
Should I take it to a Nissan dealer / Carmax and have them confirm that the car has not been flooded before I pull the trigger?
What else should I look for a part the steering lock issue?

Thank you all
