The 1974 Porsche 911 RS 3.0 is one of the best Porsches of the 70s, known for its power and performance.
The 1986 Porsche 930 Turbo is highly recommended for its speed and beautiful design.
All Porsche 914s from the 70s are advised against due to their low power and uninspiring design.
All Porsche 928s from the 80s are not recommended, as they are not fast, unreliable, and have a high cost of ownership.
The 1999 Porsche Boxster S is a great choice from the 90s, offering 90% of the performance of a 911 at a much lower price.
