en.wikipedia.org/wiki/Bentley_Continental_R

Bentley’s own historical material describes the Continental R as “the first Bentley with its own unique body since the R Type Continental of 1952.” That directly contradicts the article’s claim that the prior example was the 1965 S3 Continental.

Why the S3 Continental does not fit that description: contemporary Rolls-Royce/Bentley specialists note that the S3 Continental’s coachwork was also offered as a Rolls-Royce. Frank Dale’s model/history material explains that on the S3 generation, the same Mulliner/Park Ward designs were “also offered in the form of a Rolls-Royce” and that the Rolls-Royce Silver Cloud III models were mechanically identical to the Bentley S3 Continentals, with only the radiator, instrumentation and badging being changed.

So the Continental R was not the first such Bentley since an S3 Continental in 1965; Bentley’s own history places the last uniquely bodied predecessor at the 1952 R-Type Continental.

This overstates the Continental R’s place at the end of the SZ-era range.

Bentley’s official heritage material says the first Azure was “based on the drivetrain and platform of the Continental R” and “remained in production from 1995 to 2003.” That means there was another Bentley model on the same underlying platform still being built through 2003.

Bentley’s own 2003 Azure Final Series vehicle-specification sheet goes further, stating that the Azure Mulliner in the Bentley Heritage Collection is “the final model off the production line.” If the final model off the line was an Azure based on the Continental R platform, then the Continental R itself was not the last car still based on that platform.

So the accurate picture is that the Continental R was one of the last SZ-platform Bentleys, but Bentley’s own documentation identifies the Azure—not the Continental R—as the final model off that line.
