Apart from the 1988 24 Hours of Le Mans and the 1988 1000 km of Fuji (also valid as final round of the 1988 JSPC), the 88C made a final WSPC appearance early in the 1989 season when Toyota Team Tom's entered a lone car at Dijon-Prenois while awaiting their newer 89C-Vs. The 88C finished in fourth in the hands of Geoff Lees and Johnny Dumfries.
