In this month's issue they compare the 986 S, 987 S and 981 S.
Interesting comments from 986 owners that drove all the cars. I think they liked the new car as a group, but some weren't as glowing as you might expect.
All three were driven at Barber MS by one of the instructors and his best time in each model was:
986S --1:55.6
987S--1.49.4
981S--1.46.9
