AI Listing Summary
A rare 1971 Buick GSX Stage 1, one of only 124 produced, presented in an unrestored, highly original state with a rebuilt matching numbers engine. This standout muscle car includes extensive documentation, magazine features, and an additional racing engine, making it a significant find for collectors.
Condition
7
The car is described as unrestored and highly original with one repaint. It features a rebuilt original matching numbers engine, but has replacement headers, crank, camshaft, and bearings, though original parts are included. The interior is original and functional factory AC is present. Tires are dated 1974, indicating they are not new. While it has documentation and historical features, the replacement engine parts and old tires suggest it's not in pristine or outstanding condition, but rather in a very good, well-preserved state with some signs of age and modification.
