A lot.

Just look through auction/car sale sites in Japan and you'll see a ton of them.

 

I've done that, but I am really trying to find some numbers.. thanks though!

 

VGS was available in Japan starting in July 2000, in the LA-AP1-110 chassis series, for a roughly 5% premium (180,000 Yen) over the base price. (For comparison, leather seats were a 100,000 Yen option, and the BBS 6-spoke lightweight rims were a 200,000 Yen option.) Besides the unique steering system, the VGS package included different shocks, swaybars, and rear differential.

Cars so equipped were called "Type V", and carried "Type V" badging. The Type V trim was available at least through the initial series of AP2 models, ABA-AP2-100, which were made from Sept 2005-Sept 2007 (corresponding to the U.S. 2006-2007 model years). For the final production series, ABA-AP2-110 (corresponding to the U.S. MY08-MY09 models), it appears that the Type V *might* have been abandoned in favor of the Type S. However, the available literature isn't entirely clear -- Type V (and Type S) cars did not receive a special designation in their chassis number, and to my knowledge Honda never broke out their domestic sales reports by trim level.

Honda sold about 21,600 S2000s in Japan, but nearly half (!) of those were in the first 15 months, before the Type V was introduced. Also, if the Type S did indeed replace the Type V, then it was not available when the last 2,000 or so cars were being made. So I'd estimate during the time the Type V was available, about 10-12,000 S2000s rolled off the line for the domestic market. What percentage of those were Type Vs? Very hard to know, but if it were, say, 10-15 percent, then the total number of Type V cars would be somewhere between one and two thousand.
