I recently bought a 355 f-car. During my 9 month long search I used NADA GUIDES as a benchmark for the prices of 98/99 355 spiders. I found it to be very helpful and accurate. People are asking all kinds of #'s for these cars, but in the end when they finally sell them the price closely reflected given range. If a car was to be traded into the dealer, the price they would pay was very close to "low retail", and a clean top of the line car would sell for "high retail" figures. I saw this time after time with some of the deals I came close to making - the GUIDE was right on! SO, imagine my surprise when a week after I bought my car, and went onto NADA site to see how much $ I lost, I saw that the car actually went up in rice 10k! I did not see this rebound last spring. As the matter of fact the prices dropped dramatically then. I don't think it's seasonal. The car shows now to be the same price it was a year ago. It dropped in December the same 10k, and now it is back where it was. What's up with that? Did the bleeding on 355's finally slow down to a trickle? Did these cars find a plateau until the new model is introduced? What do you think?
