The 6 in your number represents the 1000 column. Thus a 327 vin would be a thousand or so further along in the production sequence. If people are willing to give the next number then we would know down to the 100 column etc. For example if the next number in your vin is a 5 (3275 for instance) and someone else has a 3274 in their vin, we would generally know that the other persons car was manufactured before yours by roughly 100 cars. The more numbers people are willing to share, the greater detail we can all have on production sequencing.there is 3 more numbers after 326 FYI. If anyone can chime in and explain how to know what number car I have that would be great.
