What should I look for?
$70k budget, at least a 2LT. Seeing plenty from dealers within driving distance for $67,000-70,000.
My questions
- Are the DTC issues I'm reading about happening only early on(sub 5k miles) or should I be constantly paranoid about the trans if I find a C8 out of warranty?
- I put 12k miles+ on my cars each year. Is the C8 more of a maintenance hog than previous generations?
- Any advice or things to look for? I see that people say the DCT filter needs to be replaced @ 7500 miles but is there anything else I need to confirm before buying a used one?

Yes, there have been some DCT issues, we don't really know how many or what percent. But when it does happen, it is a major problem.
I have 8K miles on my 23 and it has been trouble free. The DCT performs like magic. It is always in the right gear for any occasion.
The shifts are flawless and it is a fun part of the driving experience.

I've seen multiple 2020-2021 model year 3LT convertibles with sub 15k miles for under $70k.
Pay less and get exactly what I want sans warranty? or pay more and get less than I hoped but be worry free for a few years?
That's the internal debate.

Tom
But to your point, I think you can find a low mileage 2LT coupe for your price range. Just look carefully at the sales contract.
i found a ‘24 with the build I wanted for less than msrp. In almost 5k miles it’s been bulletproof.
If peace of mind is important to you, get one with even a year warranty remaining, This way before the warranty expires, you can purchase an extended protection plan. Good luck!

One thing that is only clear in the 2024 manual, but applies to all years is this - the DCT external canister filter must be changed between 7000-8000 miles regardless if changed earlier. Then at 22,500 miles, then every 22,500 miles after. Or every 24 hours of track use. Or when the filter life monitor (if the car has one) says so, Whichever is first. The rest of the requirements are, in my opinion, are clear, but scattered around, and you must look at just about every page to find them all and put it together.
Engine Oil/filter - whenever the oil life monitor says so, or at least once a year. The OLM will never go beyond 7,500 miles, so you want to see an oil change at least every year or every 7500 miles in the record.
Transmission fluid - whenever the fluid life monitor says, or at least every three years, or every 450000 miles, or every 24 hours of track use. You want to see a change at least every three years in the record if the car has less than 45000 miles.
I would also be looking for availability of an extended warranty, specifically the Chevrolet Platinum Protection Plan which you can buy from one of the two forum vendors (someone can provide their contact info). It can be had if the car is still under the 3/36 Bumper to Bumper warranty - 30 days and I think but not sure - 1000 miles before it expires. Best if the car has under 24000 miles. Someone will have to confirm it can purchased by the second owner - I do not know. I know if it has one already, it can be transferred.
The Best of Corvette for Corvette Enthusiasts
1. on a used vette u maybe close to the 3 year required transmission fluid change by Gm to maintain warranty. Cost about $900-$1400
2. estimated cost to maintain a c7 about $300 a year (had a '14 & '19) and a c8 about $900
3. would not own a C8 without N extended warranty!!!!!
C8's have 5 cameras, 28 modules, sensors, solonids snd the DCT.
The two go to people for warranties on the forum are Dennis Fichtner at Laurel Chevy and Todd Sutherland at MacMulkin Chevy. If you decide to get an extended warranty, send them your vin and ask for a quote; see what they can do and betting they will be at least half of a dealer quote.
I have the Platium Zero deductible 7 years 56,000 miles.
Warranties can be transferred if sold to a private party or a refund obtained on the unused portion if cancelled
I believe it must be purchased 30 days before your factory warranty expires (or before 35,000 miles) , I thinkwhichever comes first
Keep in mind there are price increases every year and the price goes up as the mileage increases. Also as the time goes on you maybe denied coverage because of mileage or repair history

@ "I wouldn't buy someone elses problem"
@ Extended warranty.
Thank you for the references, will reach out to them once I find the right C8.

I have a C7 and a 21 Sierra both out of warranty but repair costs don't worry me on them.

The "buying someone else's problems" comment is not new, not unique to C8, and has been around for at least 60 years. My father almost always bought used cars. I can recall other bragging about their new car and how they didn't want someone else's problems. Of course, you had to actually be able to afford a new car - and then you still had to prioritize it with other goals - such as saving money and becoming wealthy - putting kids through college (I'm not saying I did either one).
But in this instance, they may have a point. The price difference between a new C8, and a low mileage used one might be small, so its worth checking out.

Its probably easier to be brave until you have to pay 25k for a transmission replacement and wait two months or more for the arrival and installation......

op buy new unless you get certified or can get extended warranty....good luck
