This tool is designed to decode Chassis and VIN numbers for the MGB - it won't work for any other make or model or heritage-shelled cars. Due to the different numbering systems used for the MGB over its 18 year production run, not all information is available from all numbering schemes
We've put this together based on several internet-based sources, but we can't guarantee it works for every single car so if you find any anomalies, please let us know by e-mailing us at hello@classicmgb.com and feel free to share any potential improvements!
