Aantal ITR's in de states.

The question: How many ITRs were sold in the U.S. market?

EDIT: The answer to this question has been copied into the end of this initial post. Look for the red heading.

The good news: It's possible to come up with a definitive answer to that question.

The bad news: It's going to take a bit of computer skills and a lot of time.

The background:

Between a previously posted letter and personal contacts, several of us have heard an answer to this question from folks at American Honda, that the numbers sold for model years '97, '98, '00, and '01 were 318, 1023, 1347, and 1157, respectively, for a total of 3,845 ITRs. But some folks here have been looking for documented proof of those numbers, beyond that already available. It is now possible to get such proof. Here's how.

Every ITR sold in the United States has a VIN (vehicle identification number) in the format JH4DC231cySnnnnnn where:

c is a check digit, calculated as shown on this web page, where it says "What is a Check Digit and how is it calculated?" (The examples and information shown are for NSXs, but the calculation itself applies to ITRs as well)

y designates the model year of the car (V=1997, W=1998, Y=2000, and 1=2001)

nnnnnn is a sequential numbering of the cars produced (that does not have ANY relationship to the ITR numbers on the armrests)

Therefore, it is possible to use a computer to calculate the check digit, and therefore the VIN, for all possible VINs for ITRs sold in the United States.

It is also possible to take each VIN and verify whether it was or was not ever a valid VIN for an ITR, by entering it into the "My Acura" section of Acura's website. The website will indicate whether or not it is a valid VIN, and if so, will also indicate the color of the car. If someone does this, he can compile a list of all valid VINs of every ITR sold in the United States, and identify the color of each one. This will give us a total number of ITRs and a breakdown by color.

The problem in doing so is that this process involves entering thousands of VINs into the website to verify which ones were actually ITRs. This will require a fair amount of work. In fact, it might be so much work that it's impractical; I don't know. More specifically, I don't know how high the VIN sequence number (that nnnnnn part of the VIN) goes each year. If there was one VIN sequence for all Integra versions, including two and four doors, GS-R and SE and LS and GS as well as ITRs, there may be so many possible VINs to check that it's impractical to check all of them. (Integras were selling at a rate of approximately 40,000 cars a year in the States when the ITR first came out in 1997, although that figure dropped to around 14,000 a year by 2001, as shown in the figures here; note that those figures show sales by calendar year rather than model year.) But if the ITRs were only produced in a small number of "runs" during the manufacturing process, it might be feasible to check only the ranges of VIN numbers in and around those runs, so that only a few thousand VINs for each year would need to be checked instead of tens of thousands. Unfortunately, I don't have any idea how to go about isolating which portions of the sequence number series would contain all the ITRs. EDIT - since originally writing this post, I found out that there are four sequences of USM Integra VIN numbers each year, and exactly how high they go for each year's sequence for manual hatches. See this later post in this topic for details.

If this sounds too complicated and impossible, it's not. Someone on NSXprime went through exactly this process to determine the VINs of NSXs sold in the U.S. in recent years, identifying each one by color, transmission, and body style. Granted, it was easier with NSXs because it was only a few hundred each year, all using one sequence of VINs with no non-NSXs mixed in, so there were only a few hundred to check without having thousands of GS-R or LS Integras mixed in (and again, I don't know whether or not that's the case with the VIN sequence numbers used for the ITR). But still, if it's possible for someone to do that with the NSXs, it's possible for someone to do that with the ITRs.

Maybe there is someone here (or several someones here) who might be interested in taking this on. Someone with the computer skills to program the algorithm to calculate the check digit for each possible VIN, and someone to spend the time entering the list of possible VINs into Acura's website to verify which ones were sold as ITRs (and find out the color of each).
