All manufacturers have a hierarchy of cars, it is done deliberately to tempt you further up the range. No matter what you buy, it could always be bigger, faster, better, but for some reason the poor old Cayman seems to be the one that all the armchair pundits home in on. I'll bet that none of these couch experts have ever driven a Cayman, much less owned one.
I however do own one, and worse still I own the most derided version of all, the original 2.7 on small wheels. Every couch expert knows that this is a truly dreadful car, underpowered, underwheeled, and totally shackled for the benefit of the 911. Wrong.
Almost all modern sports cars are way too powerful and fast for modern road conditions, yet my Cayman retains all the tactile delight which made Porsche famous in the first place, and can be enjoyed without having to post hyper speeds on the dial. I have driven umpteen modern 911's, and would not swap my Cayman for any of them. The poster above who surmised that the 911 has morphed into something different to what it used to be is right on the money. The current 997's bear little resemblance to the older cars (and yes I have owned one of them too) and for me the simple 2.7 Cayman has more in common with the older Porsches than the modern luxo 997's do.
But yeh, what would I know, I'm only a Porsche owner, not a couch expert!
