My words didn't come out as intended. I didn't mean put an auto in all of them. I meant if they're willing to put an automatic in a ZL1 as an option (no Z06/ZR1 has an auto), then it means they're willing to give the people what they want. So it is a fair assumption that a convertible version isn't likely to be a door-slamming no.
If they did have a convertible ZL1 regardless of transmission option, it would sell well. JMO.
