I looked on Cargurus.com - normally they have the most Ferrari listings. There are 7 red Spiders for sale in the entire U.S. Look for prices to climb.
This one surprised me today. From what I recall, it was a gated but nothing special, at least nothing worth $150k. I saved it out of curiosity. I think it was listed about two weeks ago. Image Unavailable, Please Login
