Either blatant ignorance or that curious philosophy "I don't mind it's slower if it looks faster/cooler" (as in the 'huge wheels syndrome').

... but than i'm pretty close with the vectra wich was also designed by Wayne Cherry... the calibra was based on the same platform and shares the dashboard so i get a little bit of that calibra esperience ... ... you can see what a revolution it must have been at the time, and with a 0.29Cd was great in 1988 but it's still quite good today.

Quite true, Calibras and Vectras-A shared platform, engines, and most of the streamlining. Some mating experiments have proved DNA compatibility :



In fact the Vectras were slightly favoured in the engine department, as the '88-91 Vectra-GT/Cavalier SRi got the 20SEH version of the SOHC 8V engine with 130HP, while all SOHC Calibras had to make with the 115HP C20NE. The camshaft, pistons and ECU now inside my 8V Calibra came from a Vectra-GT donor.

... do any of your cars have an undertray? i have yet to find any picture of the calibras undertray and i heared not all calibras had those. since the similaritys between the calibra and the vectra i wonder if a calibra undertray could (be made to) fit my car... i do have a custom undertray already but it would still be nice to see what opel originally came up with ...

My cars came without OEM undertray. I've only seen it under 16V C20XE Calibras, and only rarely, as people tend to discard that piece to get easier access to the engine from below, or because it brokes with age.

I'm not sure if it's a plug&play affair in the Vectra-A, but with some DIY fiddling it should fit. The reference is GM 90 487 258 or EPC 2 12 626, if I remember correctly it costs about ~350€ here in Spain.





This is the detachable central piece for access to the oil pan:
