The cult of the air-cooled 911 is incredibly strong — look no further than the astronomical prices of vintage 911s for proof. Generally speaking, über-faithful Porsche 911 enthusiasts don’t care much for change. Which is why you’ll find non-air-cooled and non-911 Porsches going for a lot less cash — 914s, 944s, 928s and the lot can regularly be found for under $20,000. Hell, even the super-rare performance versions of those cars — numbering in the hundreds — are still a bargain compared to a, relatively speaking, garden-variety air-cooled 911. We went out and sought out those rare, offbeat cars because they’re equally deserving of collecting.
1973 Porsche 914/6 Conversion

What We Like: A joint venture between Volkswagen and Porsche, the 914 was criticized for its angular design and lack of power when equipped with the basic VW-derived flat-four. Porsche, though, built a quicker six-cylinder in lesser numbers, which has now become quite the collectable. While this particular example is actually a conversion of a basic model to six-cylinder spec, it’s a super clean restoration, and it comes in at a much lower price than original 914/6s.
From the seller: “Built from a one-owner 1973 chassis taken to the body shell, and built from scratch to create the ultimate 914. It started with welding in a 914 GT chassis stiffening kit and pre-drilling the oil cooler, air conditioning condenser, air conditioning compressor, and oil tank holes. Then welded in the dual club sport mount to handle the power of the 1992 964 3.6.”
