Yes - this is what I understand to be the Piper GT

The astonishingly low - and quite rarely seen - GTR is, as Stephen says, a rather different machine altogether.
Even having seen pictures before, the first time saw one for real, I was still amazed at how low it looked when one is standing next to it.
Is there actually any connection between the somewhat Lotus 23-like sports racer, pictured above with Chris Atkinson, and the other Pipers discussed here? I'd never linked them in my mind - thinking of them as different marques - although I confess to not knowing a great deal about any of them.
