New vehicle discount with dealer

Hello together! I intend to buy a new Harley (Touring Model or Softail) soon. What experiences did you have in the price negotiations of a new vehicle with the dealer ? Did you give a motorcycle in payment, also a foreign factory ? How much “percent” discount did you get on the new price ? I live in the Rhine-Ruhr area and would of course be particularly interested by the offers of the local dealers . I look forward to answers !! The hand to the greeting ! Jupp
