Check out FerrariAds. if any one is looking for a clean Argento silver CS. Surf http://www.ferrarichat.com/forum/vbclassified.php?do=ad&id=7442
$165 seems a little far fetched. A yellow one just went for around $125 with less than 12k miles. Two with 20k miles have gone for under $120 at Ferrari of Seattle. Even at $10k penalty per 5k miles, still high, but I am being extremely generous. Nice looking car, but I wish you good luck.
Matty if you knew the market, you'd also know that 2nd CS at F of Seattle did NOT sell as the owner decided to keep it. And you forgot to mention the CS at F of Tampa for $159k w/ 14k miles that sold in a matter of days. There's also a steady stream of interest for both the rosso dino @ $175k and the rosso scud w/ stripe at F1 in miami @ $169k as my PM box is nearly full.
The insurance companies seem to agree with your assessment. Very clean cars with under 3K miles are in the $160K to $180K range. If you can find one of these for under $150K, I think that's a very good deal.
