2016 C2 of the Year Finalist
Thanks so much guys. You've been a tremendous help. I do have the VIN on the car: VIN #1G1YY32G535119024 How do I get to the GM inquiry site to find out what repairs have been done?

2023 C5 of the Year Finalist - Unmodified
The only advice I would offer add to the great suggestions you've had is to take a look at the codes. The C5 has a diagnostic system. Run that and it'll show any problems. You're looking for a "C" code if anything is bad. The H codes just mean it had a fault that cleared. The code reference shows which system has a fault.
Mind you, this may frighten you unnecessarily. If the car looks good maybe its best just to go for it
Corvette Codes
To list your codes, turn the ignition key to the ON position, but don't start the engine. Clear any present DIC messages (like Door Ajar, or Service Steering Column) by pressing the RESET button. Then hold the OPTIONS button down, while pressing the FUEL button 4 times. This will get you into the CODES section of the DIC.
The computer will automatically display all the codes your car is or has created. It will cycle through each code every 3 seconds. You can watch it display codes for every module in your car. If you want to write them down, go ahead. Any code that ends in H is a history code - something that has occurred in the past but is fine now. The computer is very sensitive and would throw a code if you turned the radio off while tuning it.
Once the computer has finished going through all of it's automatic codes, press RESET to enter Manual Configuration. It should start with a module and show "NO CODES" or "# CODES". If it shows a number of codes, press and hold RESET until it displays "NO CODES". This is how you reset your codes.
