    Have seen this many times in Gaydon, and i still think that with a little tweaking here and there it could still be a relevant car today.

  2. Mikey C says:

    Quite cool looking, the front end looks quite sporty too.

    I love the fact that it is described as the “Austin Morris Princess”, what a complete shambles BL made of their badging around this time!

  3. Nate says:

    A pity the Princess never received a similar front-end treatment to the Triplex 10-20 Glassback from the outset (along with a hatchback and other bodystyles, more potent engines, etc.) as it looks quite appealing compared to the original.

  4. Robin Vanags says:

    It’s bold & imaginative (the ‘chevron’ rear indicator design for example. Agree with JonBoy, it needs a little tidying-up here & there, but having seen it at B.M.I.H.T., Gaydon in the late-nineties, I’m pleased to encounter it again in the new Collections Centre at the re-named British Motor Museum.

Have your say...
