There were extensive upgrades in equipment levels when the Series 2 was introduced. Some of them have already been covered. The Execs picked up a few equipment items already mentioned, minor cosmetic changes and little else. The Berlina picked up a fair bit of Series 1 Calais bits. Leather wheel, satin silver interior highlights, foglights, 16 inch alloys (previously 15's), chromed rear number plate surround, black insert in lower rear bumper. The real money was spent on the Series 2 Calais. The factory decided to market it as a "European style sports sedan" instead of just a luxury model. The most obvious changes were:
1. 17 inch 5 spoke alloys (previously 16's) 2.New front bumper facia, upper and lower grilles 3. SS style lower body kit. In the case of the front bumper, the spoiler is moulded as part of the bumper facia. 4. FE 1.5 suspension, slighter firmer than standard, which was reported as being a better set-up than FE 2 for a car like the Calais. 5. Black headlining and trims. 6. SS style leather wheel. 7. Unique tail-light and rear reflector design, with the reflectors moved into the lower bumper and accompanied by a new design of bumper insert.
Just to confuse matters various limited production runs of Equipes, using bits and pieces from previous models, were released during the Series 1 and 2 production. Not sure, but there might have been Lumina's as well.
