I loved that Mustang, Vampirella or Heartbreaker as it was also known, and this seems to be a P6 version of it or rather it reminds me of it, so a big thumbs up from me combining two of my loves from motoring history.
First car - bought in 1977 1968 Rover 2000TC JPR 196F
Second P6 - white 3500S - ?
Third P6 Monza red 3500S 'Thunderdog' - ERU 313L
Fourth P6 Lunar Grey 3500 - current car - 'Sparky'
