The photographs were taken at the start ramp of the Raylor rally held in N. Yorkshire in 1979'ish. As for technical spec. I cant really remember that much about the car other than it was built with the clubman in mind ( keeping the cost down ) using the single cam engine ( although it was developing 180 plus BHP. ) it also lacked wheel arch extensions. Of the intereor one thing I do remember was that it all looked quite standard , particularly the instrumentation. The group of 4 instruments ( oil pres. temp. etc. ) normally found mounted low down in front of the gear lever on HS road cars had been placed higher up in between the two air vents presumably to make them easier to read when flying through a stage.
When Jim McRae got a DTV works drive (1980 ?) Tery Kaby drove SMT 1 but by now as you can see in the magazine scan below it has sprouted wheel arch extensions and I think it was running in group 4 spec. and he used this to win the castrol / autosport championship..........unless of course this was a different car with the SMT 1 plate , after all the Group 1. SMT Magnum also sported this number.



Hope this is of some use to you,

Cheers, Neil.
