Here is what I have learned in the car business.... Not every deal, vehicle is the same. There are two ways to sell cars like these:
1. Do the normal games, increase price, decrease, etc.. Play the game like you would any other marquee.
2. Build a reputation providing great cars at great prices and move them quick.
I have been involved in buying and selling NSX's for 12 years now. I've owned 24 and #25 is going to be here this weekend hopefully. The key to buying and selling specialty cars ( in my opinion ) is doing it like #2.
These are such small market vehicles, so doing things like you did here is noticed and absolutely frowned upon by just about any person buying one of these. I buy and sell these due to my passion for the car and that the market is and will be strong on them. I buy them cheaper and needing work and put them through our shop, make them great and re-sell. Do I make money doing this? YES I don't do it to lose. But I also don't high gross or inflate pricing if I had it listed at a lower price. There were several times I could have pulled the ad and listed it for more and easily gotten it. For instance the white 00 that "Ric" bought from me. I sold that in a couple hours for a good price. I had offers on it for 3-4 days after he sent the deposit those offers were 3-5k higher than asking price. And that wasn't the only time that happened. the 02 I sold to "stormrider" is another example.
Dealer to dealer - the price increase I am reading about is what is hurting you here. Although I understand it I just would not do it in a small market such as nsx's F cars, etc.
NSX prices at auctions are climbing for sure.. But if you buy a car at a fair price pass that along at a fair price and don't do the sales game and you will sell a lot more here on prime. The cars I list here usually don't last more than a few days.. a couple have sold in hours.
Hope this helps and clears things up a little!
