The entry
The Porsche 997 GT3 RS 4.0.
The RS 4.0 used the largest naturally-aspirated flat-six of the 997-generation GT3 RS line, built by Porsche's GT department as a limited-run send-off before the 991 GT3 RS replaced it.
It sits at the top of the 997 GT3 RS lineage.
We review your Porsche 997 GT3 RS 4.0 on the engineering behind it, its own history and its condition, not against a generic pricing model.
