My C7 (2019) was a coupe. Really liked the car and would not have chosen a Vert back then as I didn't like the Styling of the Rag top vs the Coupe.....Just rec'd my 23 HTC a few weeks ago, and it's awesome....
1) IMO, the HTC styling is better than the coupe, which wasn't the case in the C7, unless the Engine view is that important to you, but not to me..
2) When the HTC is opening / closing, most people stop in their tracks and watch the process. There are a ton of gears and moving parts, which is a potential problem, but pretty cool design.
3) I definitely have the top off alot more than when I had the coupe.....easier / more convenient to put down and no loss of storage space is also an excellent feature
4) Big difference when driving with the top off now vs the Coupe in regards to noise / wind tunnel....My wife would almost have to hang on to her hat in the coupe with the roof off, but in the HTC, and having the back window down, it's alot quieter and less windy in the cabin....
Summary, yes, it's a pretty big jump in $$ for the HTC, but if you can afford it, the HTC is a MUST IMO....
