Sorry for the late reply but have been away.
I was looking to replace my 996 C4 after it got written off by a Merc.
Couldn't find a nice C4 so tried the Cayman S in the dealership.
For the same budget it was a no brainer.
Full leather upholstery, Bose HiFi, heated seats etc etc.
30k less miles on clock, 5 years younger [less wear and tear!]
50 Kg lighter [0-60 5.8 secs compared to 6.1] making it quicker.
Mid engined, road holding impressive.
OK less Horsepower but I don't need to do the extra 10mph top speed.
I didn't really need 4 seats as i had only used the rear ones 6 times
in 12 years [2nd car has 4 seats]. My other half loves the Cayman
and said I should have one years ago [she loved the 996 but not as much]
So there you have it, I bought the Cayman S.
