I think it pretty clear some 911 owners see the Cayman as a threat and are trying to justify there purchase of a 911 or it's just 911 snobby.

Those 997 figures are some of the best I've seen compared with the worst Cayman figures I've read. Having just sold a 996 I pretty sure the Cayman will be slower at the top end(bet the handlings miles better though) and its no great shock to me, but the basic 997 is a lot more money in the uk, an extra Pounds14k( or $24.k) it hardly a small amount of cash.
Other magazines mentioned how the Cayman is great value and questions the need for a basic 997.
I'd be very surprised if the person who started this topic isn't a 911 owner or has had one in the past or is getting another in the future
