1976 Inaltera GTP-Cosworth

The Inaltera GTP chassis 001 is the first of three prototype racing cars constructed by Jean Rondeau and his team under the backing of Inaltera, a French wallpaper manufacturer. Unveiled at a Paris media event in February 1976, it served as a test and spare car at Le Mans that year before racing in 1977 under number 88, driven by Jean Rondeau and Jean Ragnotti to fourth overall and first in class — the top French-built finisher that year. Retained by its 1977 acquirer ever since, it has seen only occasional use and comes with an extensive spare-parts inventory and documented history file.
