Common questions

How much does a Porsche 911 cost?

What is a 1973 Porsche 911 worth today?

The Shifty Estimate is $61,000, up 2.7% over the past 12 months. That sits below the $76,778 median of actual sales because the estimate weights the most recent results most heavily, and recent sales have come in under the longer-run median. We rate confidence low: 208 public sales in a year is not enough to be firm, and the honest range is wide. Treat it as a starting point, not a valuation.

Is a Porsche 911 a good investment?

It has appreciated 466% against its $10,780 list price. Values are up 2.7% over the past 12 months. The caution is spread, not direction: across the sales we have on file, prices ran from $50,000 to $172,995, and mileage explains most of that.

What is the most expensive Porsche 911 sold?

The highest public sale on file is $172,995.

About the 1973 Porsche 911

The G-Series 911 represents Porsche's longest production run, spanning impact bumper regulations through the final air-cooled era. Introduced for 1974 with distinctive accordion bumpers, these 911s evolved from 2.7-liter CIS-injected engines producing 150hp to the final 3.2 Carrera's 217hp flat-six by 1984. The base models offer authentic 911 character without the premium of turbos or limited editions. Key improvements include galvanized bodies from 1976 eliminating rust issues, and the switch to the robust 3.2-liter engine in 1984. While Turbos grab headlines, these naturally aspirated cars deliver pure driving dynamics that define the 911 experience. Clean examples, particularly late 3.2 Carreras, have appreciated significantly as collectors recognize them as the last traditional 911s before water cooling. The G-Series bridges classic and modern, offering accessible entry into serious 911 ownership with genuine investment potential.
