Purchase advice Porsche 996 Cabriolet

Moin! I need your competent help. I want to buy a Porsche Cabriolet for the first time in my life. Since the small change only lasts up to 25.000€, it will probably be a 996. About equipment is important to me: 320hp, i.e. from year 11/2001, sporty optics (sports suspension etc), switch, as little km as possible (since I would sell the vehicle again in case of emergencies without great value loss) I have a few questions: 1.) What do I have to pay attention to? 2.) At Mobile, Autoscout, ebay, I don’t find the right vehicle yet, are there other sources for Porsche? 3.) I have a Porsche at my hand, which would fit, however, the vehicle was 9 years in Italy, but built in D. Is this problematic for the potential resale? About a helpful answer I would be very pleased Many greetings, Holger
