Blocked Sources
jpsheet.com/chassis-decoder: ER34, ENR34, and HR34 are not in the jpsheet.com chassis database. The site returned its generic chassis-decoder landing page for all three codes. Impact: Low — jpsheet.com is a per-VIN lookup tool, not an aggregate production data source.
auc.autoworldjapan.com: Auction listing site. No aggregate production statistics are published on this site. Full VIN-level data requires a member login. Impact: Low — auction sites do not publish historical production totals.
Files Updated
- site/registry/hr34.html — total VINs corrected from 14,937 to 14,938; Series 2 corrected from 100 to 101 units; all related text and meta tags updated
- site/registry.html — HR34 card total corrected from 14,937 to 14,938
- projects/overrevving/data/vin-data-full.json — already correct (source is the authority); no change needed
Key Insights
- ER34 and ENR34 are accurate — no changes required to registry pages or data files
- HR34 has a 1-unit error in the total (14,937 should be 14,938) and Series 2 count (100 should be 101). Both registry pages and the landing page have been updated.
- No color cross-verification was possible for ER34/ENR34/HR34 — the supplementary source (vin-supplemental-data.json) contains only BNR34 GT-R color data
- The variant-sum deltas (111 for ER34, 25 for ENR34, 20 for HR34) are inherited from the source data and reflect special-order/prototype vehicles not categorized by variant — these are documented, not errors
- Both sources agree on ER34 and ENR34 totals; HR34 shows a 1-unit delta attributable to the Series 2 range count
