1) Are Chev dealers that sell the C8 Corvette required to have a "trained" C8 service tech on site? Or is it a case that they should but some (perhaps smaller dealers) may not.
2) If one purchases a 30 mile left over MY2023 that was built February 2023 new off the showroom floor in February 2024 would the DCT full flush be required now in two yearsrather than the three GM stresses? and when would you want to do the 1st oil change PDQ?? say in a month or two after you click over some amount of minimal break-in miles.
Thanks.

I don't remember the details but I think yes they also were required to buy tools to work on the car but after 5 years some of the posts here sound like some dealers don't have a "Corvette tech"

Interesting question. I think technically, the requirements in the Owner's Manual start from date of delivery. So, if purchased and titled as new in Feb 2024, the one year requirement of the oil change would be Feb 2025, or when the oil life monitor says so. I'm not sure when that monitor starts ticking, but it includes time. The transmission drain and fill (no such thing as a Full Flush) would be Feb 2027 or when the FLM says so. No harm in doing it early if you want. The DCT external canister filter change, which includes the Hydraulic System Flush as part of the procedure, is based only on mileage, so that would still be between 7000-8000 miles regardless of whether change early.
A Chevy dealer cant order any Corvette without at least one trained Corvette tech. I have read stories where Corvette owners have a problem and stop at a dealer in Podunk USA and can't get it worked on for this reason. They then have to drive or flatbed the car to the closest dealer with a certified tech. Not all dealers choose to sell Corvettes. Years ago the dealer where I lived did not sell Corvettes or Camaros.

There are two different certifications for dealerships for Corvette, one for sales and one for service. So no, just because a dealer can sell Corvettes does not mean they are certified to service them. When you search for a dealer for service on the Chevrolet website it's listed as follows:
Corvette Certified Sales
Corvette Certified Service
As to your 2nd question, the 2 years or 7500 miles for 1st service starts from the "in service" date, which is when the car is sold to the first owner. I believe the 3 year timer on DCT fluid change would be the same, but if it were me, I might go ahead and have the fluid changed at 3 years from the build date just to be safe. Maybe just have it done at the 7500 mile service as after that DCT fluid change is every 3 years.
To clarify - the two years is the expiration time of the first free service and there is no expiration mileage for claiming the free service. It includes an oil change and DCT external canister filter change.
But the timing of expiration of the first free service has nothing at all to do with the required maintenance. Specifically, there is no "2 year service requirement" for the engine oil, DCT external canister filter replacement, or fluid change.
The requirements are as follows:
Engine Oil - When the OLM says so, or at least once a year.
DCT external canister filter - Between 7000-8000 miles regardless if done earlier. Then at 22,500. Then every 22,500 miles after. At 45,000 miles. Every 24 hours of track use. Or when the Filter life monitor says to. Other than track use, there is no time requirement.
Transmission Fluid - When the FLM says so. At 45,000 miles. At least every three years. Every 24 hours of track use.

This is actually something we all missed. Engine oil is supposed to be changed once a year, I think I might push the dealer to go ahead and do an engine oil change as part of the sale.

It just makes me wonder how the oil life monitor is initiated. Its very good at timing out after 1 year, if not sooner. But when does it start ticking? Is it set to 100% at date of delivery, or does it start ticking when it comes alive off the assembly line? I have PDI form - it does not say anything about setting or resetting any of the on board life functions (oil, fluid, DCT filter).
Frequent oil changes support the upkeep of engine lubrication, cleanliness, and overall performance. They are a crucial component of automotive maintenance to stop engine wear and increase your car's lifespan.

Pretty sure it starts ticking when it is started the first time.
Nothing saying the new owner shouldn't reset the counters when they buy it.
No,nothing says you can't reset them. They just say to reset them when the respective maintenance has been performed. And include instructions about what to do if accidentally reset. The only one that appears to use time though is the engine oil life monitor (based on owner experience). Even though the manual says change the fluid at least every three years, it appears that time is not a factor in the FLM calculation (again based on owner experience). And, the DCT filter life monitor system "is based on the number of miles driven as outlined in the Service and Maintenance section" so time is not a factor for that. So resetting those would only discount the miles at delivery which should be low/negligible anyway. Resetting the OLM could discount a good bit of the 1 year since a car could sit unsold for months. So, that's a case of owner use your own judgment. Reset if you think its ok to discount 30 miles of driving in xx months (the OP case) and start fresh.
Much appreciation to all that have contributed, thank you.
I will do the 1st oil change this summer after a few initial driving only miles. The car has not been exposed to any drastic temperature variances other than for the 36 hours it will be in (enclosed) transit. I am leaning towards doing the DCT cannister & transmission drain & fill summer of 2026, when mileage will be at or below 7500 by that time. So perhaps early by some calculations but safer too.

Just be aware that, according to the manual (whether it makes sense or not), if you change that DCT filter before 7000 miles you need to change it again between 7000 and 8000 miles. According to the manual. Which includes some strong language about impact on the warranty if you dont do that. I can see arguments about tolerance - is 6999 to soon? All I can say is that the 7000-8000 miles already is a +/- 500 mile tolerance around the nominal 7,500. So we could go on and on with tolerances on the tolerances.
I go to a dealer that does not have a corvette certified tech, however I know their master tech has changed out at least two transmissions and handled other issues.
My car a '23 was put in service 10/27/22 so ALL my warranties start beginning that date I bought the car on 1/24/24 so I've been figuring out how much warranty I have left and since it was certified that changed because 2 years was added when they certified the car. They changed the oil/filter but not the DCT stuff because it was too early. I've got until October to get the 2 years freebie (I think) and the 7500 will be on GM (I think again) I am still confused about the 3 years service any help out there will be greatly appreciated
