Hi Dave, I have x3 Prestiges myself so do know a bit about them!!
Forgive me if the following copy sounds a bit hard going, I'm about to
go out for the evening and am typing this quickly and as it flows which
shows how disjointed my train of thought can be sometimes!!
Right. Everything forward of the B pillar is standard CX SALOON.
For the front end parts you'll need to look at pre flared wheel arch
(pre '79) suspension and front non flared wings - noticeably different
and Robert's silver one will be the later body. In fact, the early bonnet
even has holes for x2 washers whereas later cars have a plastic feed
rail on the wiper arm for the washer with a water feed running right
through the wiper motor spindle.
The roof is unique to the Prestige whether it's a high or low top.
The front screen has a 3/4" strip of stainless steel set into the rubber
surround and this is impossible to get hold of so don't lose it - the same
for drip rails along the roof guttering down to the rear wing. The door
capping and window stainless trim will match in length to an estate.
The doors are 95% Safari but the glass and window frame is arched
downwards to meet the line of the standard saloon rear 1/4 glass whereas
the estate door is square cornered and thus has a different door glass.
A tidy repairer can merge a good Safari/familiale door with the door gutter
frame and it's Prestige glass saved from a duff door.
The C pillar trim is wider and unique on the Prestige but takes the extra
length still left between the longer rear door AND the longer rear 1/4
wing so that the standard CX saloon 1/4 glass can be used. The bootlid is
standard saloon too. The rear wheel spats on the Prestige should match
a Safari/Familiale too but I haven't messed around with these to know
100% for sure.
Right. This leaves the rear 1/4 wing skins which are Prestige specific.
I guess the lower section of a safari wing could be stitched in as basically
this is what Citroen did when making the Prestige - running a saloon
bodyshell onto an estate chassis BUT
BUT this is very simplistic as
the chassis and rear subframe suspension arms/hubs/pistons/brakes are
saloon NOT estate. Exhaust will be shared with the estates too.
phew - typed all the above in 2 minutes and will add (hopefully more
coherent) additions when I see my Mac next!!
