Wondering if the original poster has had any luck finding the Wolf car? There was a post on Reddit in 2017 from someone trying to verify a NSX as the one from Pulp Fiction, but it drew no conclusion after 13 comments

Also there is this thread about the license plate

I just recently learned that the movie car was a 1992.
Also found out there were only 103 NSXs in 1992 in silver/black imported into the USA (I have not been able to find how many were sold in California, guessing less than half).
In viewing the 2 short clips from the movie it is hard to see if the roof is black or silver, but I just recently found a top view of the NSX used in Pulp Fiction that not only showed the roof was painted silver, but that the color silver was a lighter shade than the original silver in 1992 indicating they probably repainted the entire car. (Note: The original was more of a "grey" silver, and the movie car is more of a "white" silver).
I have an interest in this thread because the person who sold me my 1992 silver/black NSX in LA over 10 years ago said that it was the car used in Pulp Fiction. I never thought much about it, but he had WN WOLF license plate on it at the time, so I guess he believed it. I never thought much about it because I thought they used a 1991 in the movie. My car not only has the roof painted, but the entire car was repainted over the original and I recently had a little spot come off, revealing the darker original silver underneath. So maybe it needs more investigation after all.
As an aside, I have read some posts on line that suggest Robert Redford used to own a 1998 Black/tan NSX-T. Only 5 of those were imported into the USA (and 1 automatic). One in 5 chance on that one I guess, ha.
