I got to sit in one last month at a dealership exhibition of the new car which was provided by Chevrolet/GM. They put out a nice spread of gourmet finger foods, meats and cheeses and it was supposedly by invitation only. although they never asked for my invitation.
My brief time in the car left me with a positive impression and the interior was more comfortable and a step above my 2017 C7 Grand Sport in quality and materials. Seemed to be a bit more legroom, and the seats were more comfortable also IMO. Still low to the ground however.
As for the styling, overall well done with just a few too many creases and lines IMO, especially in the rear. Typical mid-engine design with a pretty large "behind the door" area necessitated by the layout. Build quality looked great for the price.
The car on display was $89,000.
As for the lifting mechanism, I think it's a good idea, but in my experience, unless the new car is lower, maybe not really necessary. My C7 actually has a bit more ground clearance (about 3.5 inches) than did my C6 Grand Sport. I do have an aftermarket protective plate under my carbon fiber front splitter, which has prevented damage at least twice in 12,000 miles. There are also air deflectors under the body that scrape but are designed to do so and are considered a wear item by some. You do have to approach some driveways at an angle and exhibit caution from parking lot blocks. Speed bumps have not been an issue.
