Okay... Show me a 2003 with 13K Miles for under $66K.

In all fairness, you are ignoring the difference between ASKING prices and SELLING prices. When you ask what a car is worth, I assume you are referring to SELLING prices. Ad listings show ASKING prices. These are customarily posted with the expectation that they will be negotiated downward for the actual sale, with 5-10 percent a typical amount of downward movement. So cars listed for $69-70K can very likely be bought for under $66K. Also, anyone can ASK whatever they want for a car; they can post an ad for $100K - that doesn't mean that the car will sell.
When I see a bunch of listings on Autotrader, I can tell you what a realistic SELLING price is. I start with cars of the same year and approximate mileage. I look at the general distribution of the prices, and eliminate any car that is not representative (such as the automatic, or something heavily modded, or unusually low or high mileage). I then toss out the top quarter to one third of the prices as "wishful thinking". What's left is the representative range of ASKING prices. Subtract 5-10 percent for the difference between asking and selling prices, and you get an estimate of what the car realistically might be sold for.
For example, right now on Autotrader you have 7 2003 NSXs (excluding the one with the automatic and the one with 28K+ miles). Two are $69-70K, two are $72-74K, and three are higher in price. So I would toss out the last three, and say that asking prices are typically $69-74K. I would then conclude that most of these cars can be bought for 5-10 percent less than this, which means $62-70K. The $66K you mention is right in the middle of this range - which is why I said that it is a fair price, neither a great bargain for the buyer nor a steal for the seller. Frankly, if I were selling a 2003 NSX-T with above-average miles (e.g. 13K), and someone offered me $64K for it, I'd accept the offer without any hesitation, and I'd be very happy.
Of course, you don't have to take anybody's word for this. If you're considering selling your car, list it with whatever asking price you want - $69K, $75K, or more. If you end up selling it for something higher than $64-66K, more power to you! And if you don't, you can always lower the price after a while. Just don't be surprised if you find that this description of the market turns out to be very accurate.
