Isn't that what you came here looking for?

The C7 isn't perfect. But it's also not a complete piece of crap. I'd be disappointed if I had ALL those problems, but I don't, and I doubt anyone else has ALL of them.

If you pick your vehicle carefully you can avoid a lot of the problems. For example, avoid the 3LT and you avoid the dash issue. You said you're looking for an automatic, so make sure it's had a triple flush, and ideally one that is either a) low miles or b) spent most of it's life with a Range device to disable the AFM and you avoid all the AFM problems. Get a good PPI so you don't buy someone else's torque tube problem (coupling and bearing issues should be easy to pinpoint).

You're not looking at GS/Z06 so you can ignore all the overheating and rim issues.

It seems the main undetectable and unpredictable issue is the infotainment bonking out, as there seems to be a supply-side issue with GM to get new units. These cost what ... $2k to replace? We're talking about $40k+ cars here so that price shouldn't be a complete showstopper. There is an Android replacement unit but then you lose the hidden cubby and car-specific settings.

Personally, I'm coming the BMW, Audi and Ducati world so I'm used to living with the potential for frequent and expensive repairs (not to mention maintenance). By comparison, I find the C7 to be a simpler and more reliable machine. Maybe you don't see it that way, and have a lower tolerance for problems. I get that, and I hope you can find what you're looking for.

How many C7's were sold, how many opinions did you read here ? Think about it for a minute.

BTW, my 2015 C7 has only had one issue to date,

None, that are worth mentioning. Reading threads here will clue you in on general, possible concerns.

Absolutely, all corvettes are just pure junk. That is why the car dealerships are full of brand new corvettes that can't be sold. They will eventually all be sold for scrap I heard.

I think you forgot - did someone sit in the driver’s seat? If yes, it’s fart infused and will need to be replaced.

Contrary to the expression by a few poster's here, the C7 is NOT a POS, and the litany of problems laid out is the inventory of things that might go wrong with C7's. BUT problems are rare and the car is extremely reliable, well engineered and well built. With the exception of the Z06/GS wheels that crack. Apparently, that is a thing. And the 3LT dash bubbling. But I have owned two C7's and currently own a 2017 Z51 M7 1LT. The car is brilliant and a serious joy to drive. The shift from 2nd to 1st is a little cranky when cold, and the front tires scrub in low speed (think parking lot) maneuvers. I replaced the stock shifter with the MGW short throw, and swapped out the throttle body for a Soler unit. These mods make the car more lovely and lively. And for long trips (I circled the western half of the US, top to bottom) this is one of the most comfortable cars I have ever driven. It works well as a very competent GT when you need it to.

No Corvette is perfect, but my 2019 GS is a joy to drive. I've experienced the cracked/bent wheel problem and I've had to buy new forged wheels along with replacing the Michelin summer only tires with Michelin all season tires. Even with all that, I'm very happy to own my C7, even if it's an A8. Maybe so many used C7s out there for sale is from people trading in for C8's. Not for me, I like the C7.

Other than wheels, my 2017 GS is not much of a problem at all.
I bought the car with more than 50k miles on it, and I'm probably the 2nd or 3rd owner.

The Torque Tube problem was taken care of by the dealer.
I later found cracked & bent wheels, and a neglected front alignment.
The black screen of death was brought back by wiggling a few plugs.

All my other problems were caused by hitting a large piece of debris on a dark interstate.

This is my 4th Corvette.

I bought a C5 about 15 years ago, drove it about 3-4 years and traded it for a 2012. I drove the 2012 about 8 1/2 years and traded for a 2017. I properly maintain my cars and don't abuse them. The only things I had to do besides oil changes, tires, batteries etc were a broken glove box latch and one a/c recharge. Total mileage was probably about 50,000-55,000. My only complaint is the cost of tires but I knew that. YMMV

'15 Z51, M7 3LT - Vert - ZERO issues. This is my 2nd C7 in the 3lt package and have had NO issues with leather de-lamination. I agree with an earlier statement. If 3 people have an issue it suddenly becomes a major cause for concern. Well, I didn't even think twice about it. Glad I didn't!!! I got a ROCK SOLID ca that's fun to drive. You take care of it and do all of the maintenance with GOOD materials, run proper gas (mine ONLY sees Mobil 93). = Drive and enjoy

The only problem I had so far with my '17 was the gas cap got stuck. I only had 1/8th of a tank too.
I MacGyvered the lock mechanism as the solution.

I think you're overreacting to the number and frequency of issues with c7's. Every car has a different history and most will not have those issues, except for the 3lt dash separation and tensioner leak which seems to be common but usually would have been addressed by now.

I just got a 2015 z51 supercharged by ECS and it's amazing. Clean, perfect, no issues with it at all. Engine sounds like a sewing machine.

What BS.
The C7 is a great car. There were more than 180,000 C7s built so there's plenty to choose from in the used-car market. A VIS report will tell you if certain warranty work was performed to take care of the torque tube or shudder problem, keeping you from an out-of-pocket expense. A CARFAX report might also disclose this.
Shop around for a 2018 or 2019 C7 to get the latest upgrades, including the front camera. And, buy a Range device to prevent AFM lifter issues if you get an A8. I have a 2019 2LT GS. Yes, I replaced my wheels. Yes, I replaced my summer-only tires. Other than that, no problems or issues. This is my 2nd Corvette, joining a C3 that I bought new and still drive. The C7 is a great car.
