Hi ray - and welcome to f-life. I have driven several excellently maintained examples of both the 330GT and the 365GT2+2. I love both, but they are different cars.
The queen mother is not a sports car. It is the ultimate 1960s grand touring car; it can go all day long at 120-130mph on the autostrada. Once you get accustomed to its size (I believe it is still the longest Ferrari ever made - 3" longer than the 612 Scaglietti), and if you're driving one that has fresh suspension rubber, you can actually push this car thru high-speed sweepers and induce drift that is easily corrected. Even though the steering is power, it gives a lot of feedback and is not vague (so don't buy one that has an oozing power steering pump or clapped out tie-rod ends). You can travel in style, very comfortably, with three friends and a boatload of luggage in the trunk (or some dead Italians in the trunk, depending on your line of work).
The 330 has the feeling of a much smaller car, even though it is a 2+2. It actually feels like a sports car and can be treated that way. It's motor is a sweet, revvable unit. One noticeable difference between the two cars is how much more torque the queen mother appears to have over the 330. You'll see the phrase "pulls like a freight train" used often in QM sales ads; it's completely true (unless its a tired motor). True the 365 motor has to pull more weight, but it does so and then some; it's power band is big, and it will give you that "push your cheeks back" feeling over a lot of the rev range.
You'll notice my theme of buying a good, well-maintained car. So many of the QMs and 330GTs have gotten a bad rap over the years simply because a reviewer drove one w/ a tired motor and/or reamed out suspension. Buy the best car you can and insist on a PPI. Because these great old 2+2s were at the bottom of the so-called "market desirability" heap for so long, there are a lot of cars out there with massive deferred maintenance issues. On the other hand, they are pretty easy to work on.
I don't keep a close eye on that particular market anymore, but I would think that anything over about 125k would get you a very nice 330GT or 365GT2+2.
I have also pm'd you about one of the sellers you mention.
