Purchase 996 Targa

Hello together I looked at a really well-kept 996 Targa at the PZ, EZ 1/05, 41,000 KM, last inspection at 31.000 KM. Except for a “knister noise” from the back seat area or possibly also tailgate I noticed nothing negative. The PZ would give me 2 years approved guarantee, the proud price for the really well-preserved “favorite piece” would be 44,000 Euro. I worked extensively on the engine problems of this series (KWS etc.). PZ already a new Simmerring. Do I have to keep something in mind? Is the price still OK? I would be very grateful for hints, many greetings Wolf
