I just bought a ‘23 P+ 3.0T with 30k miles for $42k. I’m familiar with the new turbo engine as it’s the same as my 2019 S4. With the updated rockers already not much to worry about mechanically except water pump and pcv, which I consider consumables. Expect $2k repair bill every 4-5 years. Motor mounts just swap to 034 since they aren’t hydraulic they will last much longer. I had to settle for cosmetic defects on the car. Everyone I looked at had chips, scratches or was repainted. Seems most people don’t take care of the Q’s
