Just looking at the Alpine (cars) entry on Wikipedia and I see that it claims the Espace was built by them!
"Fortunately, the Alpine factory in Dieppe continues to expand: in the 1980s they built the special R5 Turbo cars, following the rear engined formula they have always used. They built all Clio Williams', Espaces, and RenaultSport Spider"
I assume this is absolute rubbish and at no point were any Espaces produced in Dieppe?
Sorry to disappoint you Antony, but many Espace were built at the Alpine factory at Dieppe. Renault kept asking for more as demand increased and Matra were reaching max. capacity at the new factory they had built especially for the Espace back in 1992 when the Espace was expected to only last until about 1997.
So they started assembling extra Espace at Dieppe which had lots of spare capacity. All Romorantin production have a fabrication number starting with 'T' whilst Dieppe builds start with a 'K'.
