There are several things that should be asked what the dealership your using says should be your go somewhere else or stay with them decision. Here's a few things I've compiled to ask if I was to buy a used LTG.
1. Was it a rental? Yes I know most rentals were V6's but there's always a possibility.
2. Was it at any time modified or tuned? They can check the flash counter for this there are some ghost tunes but if they checked hard enough they could pick-up obvious changes.
3. What's the warranty? I'd demand factory warranty extension but that's just me because your inherting someone else's possible mistakes.
4. Check the timing cover for oil seap. Some of these timing cover gaskets are poorly QC'd
5. If it's an A8 demand the TSB be performed on the car before signing also if it's 10k plus miles i'd have them check for TC damage or have it in the paperwork to be covered if shudder returns. The new GM 2019 Fix is a Band-Aid fluid excuse again but there's reports they are flashing TCM calibrations.
6. Do your own inspection of suspension and undercar parts and underhood parts.
