2.6 Vectra apparently are the ones that will suit 3.2 engines with coil on plug ignition (I am looking too), but the filler neck will need altering or buy one of those offset funnels. 
If you have a 2.5 or 3 litre then an earlier Vectra with regular plug leads will suffice.

Vectra C had the 3.2, but I believe that VX reverted to plastic covers on that. Aesthetics are the only reason to chose the metal covers.

And blown crank seal instead of camcover gaskets are the reason not to use them.

Do you, or anyone know of any updates to the crankcase breather on later 3.2 engines?  Both my 2001 cars (both with FSH) have had massive oil leaks from the cam cover seals, but the 2003 Elite that I broke didn't leak at all apart from a small weep low on the LHS of the block.  My first assumption, as it had been used as a farmyard runaround in a far from cherished condition when I found it, was there wasn't any oil in it. But it did, and the engine ran very sweetly. I hadn't heard about the crankseal problem if aluminium cam covers are used, which sort of points to an underlying excess of crankcase pressure.

When such mods were fashionable, it was an unexpected consequence.

It may be suggested that poorly maintained vehicles were prone to camcover leaks, whereas well maintained examples were not... Which would be my experience of it.

When I sold my '54 it was due its second camcover gaskets at circa 265k.

My first Omega, a '51 3.2 ex Plod, that had its first camcover gaskets at around 140k. Addressing the symptoms rather than the underlying cause means changing them much more frequently, hence the idea of using metal covers because fitting them is easier than servicing the breathers once a year  ::)

It is worth noting also that the plastic covers will warp if fitted by a gorilla, something that isn't fixed by a new gasket, or metal covers, (although they're harder to warp).

At the time, metal covers were cheaper than new plastic ones. And it is noteworthy that the Vectrum C with the 3.2 had plastic covers.

In my experience properly torqued cam covers and regularly cleaned breathers = no leaks from cam cover gaskets.
