 Very few Centura's left the dealership with e33 engine code although a few examples do exist.Early KB Centuras also experienced quality issues with interior fixtures, with door trims cracking, and torn vinyl trim near stitching lines not uncommon.A story going around is that no Centura models were fitted with starter motor relays, which simply put the load onto the ignition switch when cranking instead, which reduced the ignition switch life in some cars.
