Effect of Sale Venue on Sale Prices
This analysis answers the question "what is the best place to sell an NSX?". Based on the data, Auction Houses are the worst. Now let's see why:

Firstly, the index is an indication of the "strength" of an NSX sale. I calculate it by dividing the actual sale price by my predicted sale price. An index above 1.00 indicates a strong, "over-indexing" sale, while an index less than 1.00 indicates a weak, "under-indexing" sale. I use the index to calculate the average effects of everything from special factors like the automatic transmission and a salvage title to the effect of each colors, now I will use it to break down the different sale venues.
This analysis only considers stock, clean-title, non-Zanardi NSXs to avoid skewing the index.
Auction Houses like Mecum, Barrett-Jackson, and Sotheby's represent the "Auction" category.
Sales reported privately to me, sales from the "what did you pay for your NSX and when" thread, and other person-to-person sale prices represent the "Private" category.
The results show:
- eBay sales have a lowest average index, indicating the weakest sale prices, but not statistically significant. The lowest standard deviation indicates the most consistency of sale strength.
- Auction Houses sales have the lowest average index, the 10% buyer's fee results in less money going to the seller. They also have a high standard deviation. This means the sale strength at auction houses is the most inconsistent. With these two factors, auction houses are the worst place to sell an NSX.
- BringaTrailer sales have a low standard deviation.
The auction house result is statistically significantly different than the nominal index of 1.00, validating the result. All other sale venues are not statistically significantly different from the nominal index.
