1890 Mandarin is a HJ colour which carried through into the LX colours and then onto HX. You may find a few really early pilot HZ's in 1890 like you find a few early A9X's, but 1926 Flamenco was added for HZ release. A friend of mine has the 2nd A9X hatchback which is 1890-18V, it is the car built for display at the Hang 10 500 (Sandman) in 1977 so CAMS could view it. AFAIK it is the only production A9X to be fitted with a T10 although the mod was done post assembly plant and it never got its new ID plates fitted before it left GMH's ownership.
