#26 - Robert, I had it confirmed last night by the original owner that my car was indeed supplied as a kit despite the chassis number (5LCxxx16RD) not indicating that it was a kit. Maybe chassis numbers that included the K for kit were introduced after my car was built which was early June 1987. It also explains why the V5C has the note"declared new at first registration".which I wouldn't have expected if the car had been factory built. Unfortunately I can't locate original receipts, etc and will have to try Caterham. First call on Friday indicated that they don't have records that far back but I was given contacts of their archivist, Martin Phipps who may be able to help. The engine was indeed at 1600GT but the same engine has been upgraded via cams and airflow and of course the necessary changes to ensure robustness.at greater bmep. So to the bigger picture "Are Ford Crossflow Supersprint spec cars failing HC emissions at MoTs?" Does anyone have any data on this?
