Ferrari is on target to build 6,500 cars in 2008.
Maserati will build 7,000 this year and hopes to build 12,000 in 2012. (Source: Motor Trend)
Corvette production runs between 10,000 and 20,000 per year - call it 15,000 average. In it's heyday, they sold 38,000 in '69, 46,500 in '76, 53,000 in '79 & 51,500 in '84. (Source:

Vipers have been made at a rate of about 2,000 per year, with production starting in 1992.
Ford built the GT at a rate of about 2,000 per year for two years. I'd say that is quite low comparably.
This is a great discussion and I enjoyed reading it all. I'd like to add a few thoughts about 'vette sales and the success of American sports cars.
Sales for the C6 corvette have been
'05 = 37,000
'06 = 34,000
'07 = 41,000
'08 = 35,000
C5 sales were
\97 = 10k
98 = 31k
99 = 33k
00 = 34k
01 = 36k
02 = 36k
03 = 35k
04 = 34k
C4 sales were
84 = 51k
85 = 40k
86 = 35k
87 = 37k
88 = 23k
89 = 26k
90 = 24k
91 = 21k, even with the introduction of the ZR1 which must have been close to 25% of those sales
92 = 20k
93 = 22k
94 = 23k
95 = 21k
96 = 22k
Source for all of those was wikipedia, which I realize isn't perfect. Google corvette and follow the link from the main article to the specific model articles to get the sales figures in tabular form.
It could be said that as the quality of 'vettes has improved, and as the quality relative to other sports cars improved, sales have improved. C6 has sold better than C5, which sold better than C4 (excepting the very early years of the C4). C6 vettes are awesome cars, top to bottom in the line, and cheaper than anything thats close in performance.
Viper sales in 2008 I'd guess are up relative to the previous few years?? The '03+ Vipers were as cool as Vipers always are, but behind the game for performance. The '08 Viper ACR is beating competitors by margins probably never seen before in comparison tests, and I'd guess its sold out, probably at a premium over MSRP?
The Ford GT, which I am gonna own pretty soon, holds its value better than any modern Ferrari or Lambo with even 10% of the production number. In 2006 Ferrari sold 1625 units in North America.

So while Ferrari has more cars here than FGTs, the FGTs are all, as far as I have seen, still over the original MSRP and probably close to the original selling prices. That can't be said for Mercialagos or GAllardos, or F360s or even F430s (and when the model changes, F430 prices will plummet). Never mind more common imports.
Americans are still, perhaps, loyal to or willing to be loyal to, American brands if the American brands put up quality product.
And the "crude" technology thats at the heart of the argument against American cars really isn't. The new CTS-V, the Z06, the ZR1, the Vipers all use boring old pushrods, and all deliver performance/mpg and performance/reliability that is not really even approached by any "high tech" import.
CAn you imagine how severe the beating the ACR could deal FErrari et al. if it got some real R&D money to back it? Active handling and things like that? The FGT and C6 Z06 are just better tires away from spanking the most exotic cars at the 'ring. 7:40 for the FGT and 7:42 for the Z06, on Goodyear runflats translates to very fast times on decent tires. The ACRs time, unmatched by Enzo, CGT, Pagani and so forth came with 4 tries. The ZR1s second place time came with runflats.
There are alot of challenges ahead for the big 3, but product quality is rapidly meeting or beating import quality, and there is at least some hope. I'm not naieve enough to predict glorious things for the big 3, but there is hope.
