Termi - well I'm impressed,
it is a Facel Vega Excellence. They only made them for 4 years (58-62) and not sure how many they made but was not big, about 156.
Note - no "B post" how many other cars were made with out a B post ? (and I do not know the answer)
Was told by a owner once, if you jacked up the car or parked the car on a kerb, the car would twist so much that you could not close the door easily, if not at all.
Have to try and find a hard one next time.
