I noted in the owners manual it referenced the scoops as if they were included at least on the track package and possibly all 27 6.7 models.

Looks like the cars really are rolling off and there is actually 1LZ trims not just fully loaded ones. There are 13 1LZ coming into my area so this is a good chunk of cars.

I am curious if these are all customer cars and just starting to show or if some dealers put in orders for stock units.

I am brand new to the C8 Forum Section as I normally write and respond to our fellow members in the C2 section of our Corvette Forum.

Last week the wife and I put a deposit down on a Grand Sport (the configuration picture is below) for her with our local Chevy Dealership and if all goes well are slated to take delivery in September. The 3LT and Dipped interior was a lock on this GS with the wife being insistent that this be the final configuration regardless of potential issues.

For those that are shaking their heads, it was either a 3LT red dipped interior or we are NOT buying the car. What can I say . . . Happy wife, Happy life.

I am aware of the horror stories of the de-lamination and or bubbling on the leather dash section under the windshield arc and had a few questions which I was hoping you all could me help with, so here goes . . .

What would your estimation be of the amount of time that typically passes from the date delivery of a new C8 to the beginnings of the de-lamination?

If it happens while the C8 is still under warranty, will GM repair or replace the damaged section without too much kicking and screaming?

Besides the radical use of a fitted sun shade, are there any other techniques one could use to slow down the inevitable?

For those of you who have had this happen (or know someone who has) out of warranty, what is the approximate cost to have it repaired/made like new?

Thanks very much for any information you can provide. I like to know what kind of a beating I am in for. Cheers, C.J.

I have a 2020 C8 and looking to trade it in for a Grand Sport. I have used the US build site to gather info. I was at my dealer today working on a build and 2 things came up.........

- The sales manager said aero packages are on hold for now and in fact, most cars will not be able to get them this year (he said maybe 10% or so). Any orders going in right now, will not get aero packages. Have others heard this? Are others just going to use after market aero parts?

- Black Exhaust Tips do not show up anywhere. Are all exhaust tips black as a new standard?

Thanks All,

Steve
