Porsche 911 (964) Buyer's Guide
The Modern Classic Transition
The 964 (1989-1994) was a massive technical leap for the 911 — AWD (Carrera 4), power steering, ABS, airbags, and a significantly revised suspension using coil springs instead of torsion bars. It looked similar to the 930 but was 85% new underneath.
Powertrain: The 3.6L M64 naturally aspirated flat-six (247 hp, Carrera 2/4) with a 5-speed manual or optional 4-speed Tiptronic automatic. The 964 Turbo (1991-1994, 355 hp) continued the 930's turbocharged tradition with a 3.3L or 3.6L. The RS (1991-1992, 260 hp) was a lightweight, rear-drive homologation special. The RS America (1993-1994) was the US-market RS.
What to look for: Rust is less severe than the 930 but still a concern. The dual-mass flywheel can fail. The HVAC system is notoriously complex and expensive to repair. The Tiptronic is slow but durable. The 964 RS is one of the most collectible 911s. The 964 C2 manual is the sweet spot for driving purity.
About the 964
The 1989-1994 Porsche 911 (964) is the third generation of the 911, introducing a comprehensive technical overhaul while retaining the classic 911 silhouette. Engine options included a 3.6-liter naturally aspirated flat-six in the Carrera models producing 247 horsepower, with the Turbo receiving a 3.3-liter or 3.6-liter turbocharged flat-six. Transmissions were a five-speed manual or a four-speed automatic (Tiptronic), with rear-wheel drive standard and all-wheel drive available on the Carrera 4 models. Body styles included a coupe, cabriolet, and Targa.
The 964 marked a significant modernization of the 911 platform, featuring a revised suspension with coil springs replacing torsion bars, power steering, and larger brakes. Approximately 85 percent of the parts were new compared to the outgoing 930 generation. The subsequent 993 generation refined this platform further with a more powerful engine lineup and a new multi-link rear suspension.
For used buyers, the 964 represents a transitional 911 that combines classic proportions with early modern engineering. The engines are generally robust, but the complex heating and ventilation system and the dual-mass flywheel are known failure points. Rust can still be a concern, particularly in the kidney bowls and around the windshield frame. This generation suits enthusiasts who want a relatively modern but still analog 911 with a pure driving experience.

Frequently asked questions
Is the 964 a good first 911?
The C2 manual is an excellent entry into air-cooled 911 ownership. It's more modern and easier to drive than a 930 but still pure. Budget $3,000-5,000 for maintenance catch-up.
964 vs 993?
The 993 is more refined, has a better suspension, and is the last air-cooled 911 — commanding a premium. The 964 is raw, more affordable, and mechanically similar. Both are excellent.
