Thanks to Eddypeck for his time and effort.
To check you car has the correct interior you need to check the code on the boot sticker. The trim isn't in the options it's listed to the right hand side of the paint code as two letters.

I don't believe this was ever available in the UK, only ever seen on import cars.
Grey / Red Stripe (early spec Recaro sports seat option)
GTI One In Ten Million 1988
49 Colour-stripe (Rainbow - same material but different seat shape to late spec 16v)
These are early rainbow trim specific to One in Ten... cars. Note there is now horizontal stitch across the base of the seat and they have the smaller adjustment handle, not the big "Ejector" seat type.

The door cards to go with rainbow trim just have the grey lines and none of the red, green or blue so may look like the wrong ones at first glance.

we have a BW in my 1.3 which might be black/white?
we also have a 44 interior code in the Driver?
Is the grey material on ultra red same as on ultra blue?
