I'm 75. Bought 1st C3 at 21. Two more C3 at 29 and 31. C7 Z06 at 70. C8 at 71. C7 ZR1 at 72. Just turned down chance to get C8 Z06 because ZR1 is scheduled for 2025 and I didn't want to be saddled with Z06. Once you've had ZR1, Z06 just don't light the fire. Currently have C3 custom and C7 ZR1...
I have same as yours 3ZR Sebring Orange vert, 7K miles. It has appreciated so much that I hesitate to put any more miles on it. Might consider selling at the current high price level. What a dilemma!
