The numbers aren't matching up. I got the below information off of subarusvx.com. These figures don't match up with several of your numbers, just at a quick glance Randy, Wayne, and Leo all have 4 digits exceeding production totals for their year. (yes I know there are foreign numbers to figure in there but some of your numbers are off by thousands) So either these figures are wrong or our VIN decoding system is wrong....
Or maybe I'm just wrong
