Vehicle Details
AI Listing Summary
This 1977 Porsche 911S coupe has been significantly rebuilt and modified with a twin-plug 3.6L engine, upgraded suspension, and brakes, all refinished in Seafoam Green. While it presents well with numerous enhancements, its 171k indicated miles and project car origin suggest it's a well-sorted driver rather than a concours showpiece.

Condition
7
The car was acquired as a non-running project and has undergone a significant rebuild and modification, including engine, suspension, brakes, and bodywork. While many components are new or upgraded, the odometer shows 171k miles, with approximately 1k added by the current owner. The description indicates it was repainted and has aftermarket seats and wheels. It is described as a 'mid-year 911' with modifications, suggesting it's not in factory original condition but has been well-maintained and enhanced. It does not appear to have major damage, but the extensive modifications and mileage place it in the 'Very Good' category, requiring some attention to maintain its modified state.
