5 Year Service
I also thought about getting an extended warranty so I had the GM Protection Plan checklist that a dealer needs to fill out for that.
With the check list in hand I went to a dealer very close to me, a couple miles, but one that has screwed me over and I will not let touch any car I own. They quoted me $394.22 for the check list, they said it's the usual price for doing a certified preowned checklist. They could not figure out the price for doing the lift service as they said it's not in their computer for either labor or fluid, the finally decided on $439.22. Brake system was $430.
I then went to a dealer aways away I used to use and the local club uses. Pre tax prices for the check list $250. Lift $400.54 and brakes $159.95. They also had a hard time figuring out the price to service the lift and were amazed that the C8 is now 5 years old and they had not had anyone ask for their 5 year service. Said it seemed like just yesterday that the C8 was in the show room with huge dealer mark ups on it...
I almost feel like going to a couple other dealers to see how close they would be to either of these, when you're retired you have to have things to do...
I have never been a person to buy an extended warranty on anything and usually don't follow exactly the scheduled maintenance on vehicle, instead going by how I use them/ how many miles I drive. While I have been doing engine oil and DCT filter and fluid per schedule and the air filters, I haven't done tire rotation or wipers. In the past I also never did brake fluid flushes, just sucking out the reservoir and refilling a few times until the fluid gets clear (not a good way, I know) and never had a lift system to maintain. I'm now leaning on not getting the warranty and not doing the lift or brake maintenance for at least another year or two, and probably won't even have it that long.

For the brakes I plan on removing the old fluid with a syringe and doing either the old fashioned 2 person bleed or a gravity bleed. I realize this won't get the fluid trapped in the ABS system but it will get most of the fluid.
For the front lift I'm going to remove the old fluid from the reservoir with a syringe, put in new fluid, cycle the lift a few times, and repeat the process a few times. That will get most of the old fluid out.
Moisture is the main culprit and I live in a dry area. Inexpensive brake fluid testers and test strips can be purchased. On my older vehicles I just look at the fluid for discoloration and test it. If it is good I leave it alone unless I decide on giving the car some TLC. Most modern systems are sealed with a diaphragm and not vented to minimize moisture intrusion. Many car manufacturers don't have scheduled brake fluid replacement intervals and just say to test the fluid periodically.
The engine coolant is also scheduled for replacement at 5 years on a 2020. GM has recently extended the life of DEX-COOL to 6 years in newer vehicles so I plan on waiting until next year to change the coolant. When I change the fluid I'm probably going to go with a 10 year extended life coolant.
I'm probably not the average owner. I am retired and below the poverty level and every dollar counts. The Corvette, as my motorcycles, is a toy. I have a Nissan NV200 I drive most days I go somewhere (usually flying my RC airplanes) or my wifes Honda CRV. Selling the Corvette will free up a large part of my income, not just disposable income.
Thanks for info on 5 year stuff but EVAN, It sounds like you wont keep car very long so why bother?, maybe a C9 in near future?
I have plenty of $$$$ to sustain myself the rest of my life but still have guilt about owning a $100k car. Two different kinds of thinking I guess.
The point of my post was really more about dealers pricing for service. The rest was me whining. 😀

And two (oh year not just one) of my older cars the 60 vette and 37 ford - I failed to flush the fluid for many years. And that was a real mess. Externally, everything looked wonderful and clean .... but inside moisture was doing its work.
There is, by the way, a procedure for changing the fluid in the front lift system.
Hydraulic Suspension Fluid Reservoir Replacement
Don't know why it would not be in the system.

2) OP mentioned picking up the extended warranty. It's not the same thing as a service agreement, and therefore won't save any $$$ on routine maintenance.

I bought my 2020 with 8800 miles on it a year and a half ago and I simply don't drive it a lot, I have four vehicles not counting my wife's. Her year+ old CRV has 2400 miles on it. One of my motorcycles, a 2023 has 1000, my other is a 1998 and has 16,000. Just like someone saying poor people shouldn't own a Corvette (or that's the way I took it), I don't feel I'm saving it or any of my vehicles for the "other" guy.
