This is such subjective issue. It's really not a question of "is it worth it?" It's a question of "is it worth it to you?" For me - above all - I wanted a luxurious interior - and the 3LT interior on the C7 was too sweet to pass up. I love the look of the kalahari dash from the inside and outside of the car. For others performance trumps everything and they'd rather get a "base" Z06. It's all about what you value.
