Auto dealership claims there is no disclaimer??

Hello Together I am just really on 1000 volts. I sell my car privately to a Mercedes dealer (large known car dealer). I received a purchase ticket and signed it. Here, however, neither a GTC nor a revocation and in particular the clause of the liability for defects of property and its exclusion (as it is from private to private) is not included. I called again and asked what it looks like. The seller does not think that there is any private to H ändler. I consider this to be a bullshit after 444 BGB and poked in an email for the supplement. How do you see this?
