Had my Cayman S in for service with Porsche today, rather pleased to get a brand new 718 Boxster S as my courtesy car (one of their demo cars):
My thoughts roughly as I can remember them:
If I'd never driven a 6 cylinder Porsche before, I think I'd have probably put a deposit on one (if I had the cash), it's a bloody quick car and in the right mode it does feel very very good to drive
However, the whole reason I was sold on buying into a Porsche was the 6 cylinder naturally aspirated experience you get. The 2.5 engine is great, probably the best 4 pot I've ever driven, however it's still laggy down the bottom end. On startup and revving under low load, it actually sounds quite good (better than expecting), but it's just not what I want to hear in a Porsche! There's quite a lot of turbo whistle you hear when under part load and top down.
The PDK in this was the best bit, shifts are wonderfully quick, my PDK feels like an old slushbox by comparison. The coasting feature works pretty well, coasting works a lot better than on BMWs with similar feature.
Did a mixture of rural, town and motorway miles, averaged 21mpg (I normally average 22mpg in mine), I generally drove as I would my own car, with the odd bit of testing out things, so realistically I'd probably get much more as I do longer runs
The car looks a lot more orange in real life!
