I remember seeing a review many years ago in a soft porn mag when the SE first appeared. I think it was Men Only. the writer used a great term for describing us TIV owners apparently we are from a breed known as: Auto Enthusiasticus.
Managed to find a review on the 400/450 in "Which Car" from 1991 - also have another road test on the 450 SE - nothing else for just the 400 - drop me your email address Neil and I will send across..
