Again, thanks to all for the replies and comments - all are appreciated. I've been looking at alternatives to my 360 spider since my last post, and to be frank there aren't very many choices.
The new Alfa 4C looks great, but the reviews aren't very encouraging. And my prior Alfa history (I've owned 3 - 1986 GTV-6; 1995 164LS, 1991 Spider) suggests that buying the first year of a new Alfa is an exercise best left to those with a strong stomach. At launch the cars will be priced at $70K or so - not an insignificant amount for a beautiful, but potentially mechanically untested machine.
Surprisingly, Aston Martin is offering a newly reduced price Vantage at $100K, nearly $40K lower than the current car. Apparently they are trying to reduce their parts inventory and salvaging whatever they can before a fully new model emerges. The Astons I've driven have all looked wonderful, but drive less than wonderful. If this were my pick, I'd spec it with the manual transmission, avoiding what I recall was a pretty unimpressive F1 type transmission (rough shifting, not quick to shift, really awful). It will depreciate, no doubt, but it is "age appropriate" and still a car that can be described as "eye candy". The reality is that I don't really drive aggressively much any more, and comfort and "style" are nice features (don't get old - it changes your perspective).
The new Jaguar F type Coupe (my preference) base model with some extra toys is near $80K, and that's with the base engine. Oddly the interior colors seem limited to black (some with contrast stitching) and red. I'm a tan kind of guy - bummer. Even though it's a possibility, it's not a "gotta have it" car.
The new Maserati Ghibli is a different animal altogether. More of a family car than a sports car, but it's Italian and I had to add it to the list. Even starting with a base car when you add the expected options you're again close to $80K - hard to justify.
The new Corvette and 2015 Mustang are "American Iron" with all that implies, both good and bad. On a spec sheet they are attractive, but I've never been drawn to either - call me a snob, probably true, but they don't really appeal except on price.
BMW M4 may be a contender, but again a different animal and not really a contender, but still an interesting car in the $80K range.
Someone mentioned an Audi R8 - a very nice package, but I'd have a hard time going from a Ferrari 360 to a R8. And given some friend's experience with Audi cars as they approach 5-6 years of age they seem to develop an appetite for visiting the service bay regularly. I'd rather pay to service the Ferrari, especially since depreciation should be minimal.
The new BMW i8 seems interesting, but frankly I'm not so sure I'd rate it above the NSX. Looks are fine, but I've owned many BMWs and like Audi they don't tend to age very gracefully.
So, I'm still in the hunt with the NSX. It's a matter of price and availability. The dealer says I'm #4 on the list, but until he starts taking cash deposits who knows where I'll wind up. He seems to think that delivery will realistically be Q1 2015. If the car's priced at $125K or less, it still seems like a very reasonable proposition. The key to me will be steering feel. Nothing I've ever driven has the steering feel of a Ferrari (sorry, but you know I'm pretty biased).
Thanks again for the suggestions and help. I am anxious to actually see and touch the new car. Even if the wait is a year or so, I can live with that if it's the right car.
