[The date that a car was built]

Thanks Roger, just ordered a certificate, at least I'll know one way or the other.

Very grateful for the quick response

[The date that a car was built]

I have a Triumph Spitfire which was first registered on 1 August 1980, to bring forward the Road Tax exemption date from 1 April 2021 to 1 April 2020 I need to prove that the date the car was built was prior to 1 April 1980, otherwise its more Road tax for another 8 months.

Does anyone have an idea how I could find out that build date ? I've tried the DVLA but they couldn't help.

Thanks
