I've never really 'got' Porsches, so my choice is unconventional and probably irrelevant, but the great late '60s styling of the 914 appeals to me more than any other.
They were a brave move for Porsche but I seem to remember seeing quite a few around whilst working in Western Germany in the seventies.
I like them too, can't say I've seen one in a long while over here.
Thanks - they are all Porkers I think - the 928 and it's V8 appealed to me also and I expect they will start reaching for the ceiling with their prices before too long.
