Phantom didn't make a 23 in the late 80's
that'll be a nice 70's/early 80's 23', there was a couple built with Volvo Speedmaster 'E' drives and Chrysler V8's, one also got a Mike Bellamy 'LM' surface drive and 3.8 straight six Jaguar engine (put together my Mike himself).
They were a little too easy to stuff if not driven with total commitment
