GT4 is the obvious answer, of course, but they do still look jolly expensive at £80K+. At that money you really should be looking at 997 GT3s as well, and that's not really the point of this story. A late GTS is appealing as well, though values of those are now influenced by their enviable status as the last six-cylinder Cayman: this car is for sale at £64,000...
Thing is, of course, there were plenty of very good six-cylinder Caymans before the GTS; though potentially less desirable now, there's an awful lot to recommend the plain old Cayman S. From 2013 - yes, it really was nearly five years ago - the 981 Cayman S had 3.4-litres, 325hp, 273lb ft, a 175mph top speed and a kerbweight on the favourable side of 1,400kg. It was, and remains, a compelling sports car formula.
This one is especially nice. Narrow down your search to just the manual, 3.4-litre 981 Caymans and there are five on the PH classifieds. Why this particular one? White won't be to everyone's taste, but look at the spec: ceramic brakes, a limited-slip diff with torque vectoring, the sports exhaust and sports seats. You won't find many, if any, like it.
It's been a third car - so has just 11,000 miles recorded - serviced only at Porsche and, at £47,500, is more than £15,000 cheaper than that GTS with the same sort of miles. The biggest issue we can see so far is that Carrara White is spelt incorrectly...
early 991s not far away if you're tempted. An F-Type will do plenty on the drama and theatre front, particularly as a V8, but won't be quite as sharp to drive. And you could buy a newer Alfa 4C if you really want to, though we wouldn't recommend it.
Nope, it really is quite hard to argue against this Cayman. Six cylinders aren't coming back any time soon, manuals don't look to have an especially rosy future and such a driver-focused spec is the icing on the top. It will always be a car in demand if you did come to sell, but why on earth would you want to get rid of it?
