You may have a point there about the check digit. So the check digit would correlate with appropriate serial numbers. But with multiple check digits, there would be multiple serial numbers, right?
I should also mention that a few years ago, I did check carfax with random VINs by changing the last few digits ONLY, and it would always come up with a result, but not be able to give me much details on it. So for the original poster, did you actually get REAL DATA from the VIN search?
I had no idea someone had done this before me.
The check digit is calculated by converting all the letters to its equivalent numerical value, based on a little chart I have. Then each value in the VIN is multiplied by a specific number based on its position in the VIN. The sum of all the values is then divided by 11, and the remainder is the check digit, 10 being X. So any specific VIN can only have 1 possible check digit.
And yes, on carfax you can enter just about any VIN, even with an incorrect check digit, I believe, and get a result, but the car listed will have 0 records. I made sure all the cars I looked up had at least 1 record, meaning it was produced and sold.

Good work cephoto. Thanks for doing that. You came up with the exact same number as me. Also to those of you who don’t believe the vins are sequential. Think again. When I did all of my research on CarFax I made sure to look at the first date that the car was registered. Not surprisingly the cars with way higher prouduction numbers have later registration dates.
Furthermore, CarFax often lists the colour of the car and when searching all the VINS I’d come across like 30 cars in a row with sequential numbers that are the same colour and then another 30 or 40 a different colour. This supports the notion that the numbers are sequential as well as you can imagine the factory process would be streamlined creating cars of the same colour.
In my opinion it’s an absolute no brainer that the numbers are sequential. You can also look to the engine block numbers and see that they will closely match the VIN. Again cephoto thanks for doing that research, it is another means to prove how many GS-Rs were built for sale.
As for the first few cars of each year being “non existant” we can only speculate that they are with some collection of Honda’s somewhere.
For those of you wishing to see my information supporting the number of GS-Rs made, it is here: http://forums.g2ic.com/showthread.php?187420-92-93-Gsr-Production-Numbers
I own two '92 AGPs. Both are #1590 and #2827. #1590 is wrecked and being cut up as we speak. A friend of mine also cut his up. I can get the build number from his and post it.
[QUOTE=cephoto;2169066]I’m sure many people have been wondering this, and today I have found the answer. I’ve been running VINs all day and this is what I’ve come up with…
1992 GS-R VINs range from
XXXXXXXXXXX000003
XXXXXXXXXXX003120
1993 GS-R VINs range from
XXXXXXXXXXX000002
XXXXXXXXXXX000851
1992 GS-R’s: 3118
1993 GS-R’s: 850
Total: 3968
This only indicates the number of DB2’s that were actually sold. I’m sure the first couple each year were kept by Honda, explaining why they start at 000003 and 000002.
Although I’m fairly certain this is as accurate a number as we’ll ever get, I can’t be 100% sure it’s perfect. So if you have a GS-R whose VIN doesn’t fit the range for the proper year, let me know and I’ll investigate a little further.[/QUOTE]

cephoto did his research independently, not knowing I had already done it. This is solid evidence that these numbers are correct.
