April 14 edition of Autocar compares A45 AMG, S3 S-Tronic and M235i against a bog standard Cayman manual. Some snippets below of the testing notes regarding the Cayman....
"The best drive here by a distance. Special"
"It takes a truly great sports car like the Porsche Cayman to shine a spotlight on the M235's deficiencies"
"Porsches steering rack shows Audi and BMW how to execute a flawless, progressive, system - quite conservatively, and with feel".
"The Cayman is barely quick enough to even keep up with the S3"
But because I know you ASN members like a balanced post....I have included below the comments regarding the S3 (which actually gets a very good write up).
"Seeing all the cars side by side - you would expect the Audi to be the priciest option because it looks expensive - like a million dollars in fact" (it's the cheapest on test).
"The S3's slightly lower strung turbo has more natural charm and a more obliging manner (compared to the M235i)"
"The Audi is just as stable but better balanced and more responsive in every way (compared to the A45 AMG)"
"The Audi's cabin is much the nicer, lighter place to be"
"There's a pleasingly sticky, precise front end here, and a rear that's gently mobile when it's unloaded and the ESC is deactivated. Which is about as much as you could hope for, really. Nice work, Audi"
