1973.5 911T Coupe 5-Speed

The 1973.5 911T marked a transitional moment in Porsche history, as U.S.-market cars switched from mechanical fuel injection to Bosch CIS (Continuous Injection System) midway through the model year. This change improved reliability, drivability, and fuel efficiency, eliminating the mid-range flat spot often associated with earlier MFI cars. The update also brought visual and mechanical differences, including a larger oval airbox, revised fuel system components, and the addition of rubber bumperettes to meet new regulations. While not as raw as the earlier MFI cars, the 1973.5 911T offers a more usable and refined driving experience, bridging the gap between early long-hood cars and the impact-bumper era that followed.

This 1973.5 911T Coupe 5-Speed came finished in Sepia Brown over Beige leatherette and showed 75,000 miles, though the odometer has been inoperative for years and true mileage is unknown. An honest presentation with noted paintwork throughout, including rock chips and blemishes on the front bumper, along with a tear on the driver’s seat bolster and a cracked dash pad. After sitting for an extended period, it was brought back into service in 2026 with an oil change, new battery, fuel pump, and fuel pump check valve.

Over the past twelve months, 1973.5 911T values have averaged $79,100, with a low of $13,250 and a high of $167,000 for a nicely refreshed example sold last April. I had our Spotlight Car closer to the average, but bidders saw it differently, pushing it to a strong $91,000.
