Fast Marina Magazine

Interesting pre-release article on the Leyland Marina 6 (zoom in on the 3rd-to-last photo). Claims Leyland were planning a twin carb 135bhp "Rallye Pack" option. Says the 6 was to get a front swaybar, but afaik they never did. Also has a photo showing an estate that was being evaluated, but never made it to Australian production.

Looks a lot like an FSO Polonez in the picture under the Marina Six on the cover - which isn't possible in Australia in 1973.
