Not rear mid, V10 engine...
As far as I know, 911, Cayman and Boxster all rear engine with flat 6 boxer if I am not mistaken.
Furthermore, Carrera GT is only available in manual transmission which made it even more difficult to control. But the person who was driving it was a race car driver...
Cayman & Boxster are mid-ship. Usually only those with engine located behind the rear-axle is considered as RR.
Yesteryear supercars are hard to tame & unfortunately, crap happened.
