Z&I

I'm from J'oisey meself ... a few miles from the GW Bridge.
Flood damage is easy to spot ... just need to take it to a good speed shop/Dealer and put it up on the lift ...
Tell them to look for water damage ...
Also find out where the car was when Sandy hit...Central NJ was hit the hardest.
Don't fret yourself either ... this is the winter and Z sale prices are more negotiable.
Remember that dealers don't pay much for trade-ins or auctions.
Don't be fooled by the apparent price reduction...they need to make the monthly bottom line irregardless.
Hope this helps ...
'Z's are specialty cars ... you have the advantage.
