Want to Buy: Porsche 911 from 1980s - $50,000 (Riverside)

I am looking to buy a clean (preferably low mileage) Porsche from the 1980s, 1990s, or early 2000s that you are looking to sell.
I love all Porsches, especially air-cooled 911s (G body, 964) and higher spec.
models (turbos, etc), but will consider any clean example, including 944s, 968s, etc.
I am a serious, cash buyer.
Thank you for the consideration.
