well theres only one generic picture, for a nsx from that year with that mileage it should fetch for more than double that asking price. also the websites never crack down on those 10K nsx's and there are plenty of ads on ebay where it uses photos from nsxprime members.
if you call the person who post the ad up, the usual story would be " i'm out of the country, the car is in a garage somewhere. I need a deposit to ship the car to you and it will be guaranteed, blah blah. " You than give them the $3000 they're asking for and you will never hear from them again.
This happens a lot in the supra community, the GTR community and the NSX community. if it sounds too good to be true, chances are it is.
