The Porsche 964 has steadily evolved from a once-overlooked 911 to one of the most desirable air-cooled classics in the lineup. Blending retro charm with modern tech, the 964 represents a turning point in Porsche’s history — and today, it’s one of the most rewarding models to own, drive and invest in. But before you dive in, there are a few key things to know. In this comprehensive Porsche 964 buyers guide, we’ll walk you through the model range, what to look out for when buying, and how Design911 can help keep your 964 running and looking its best with a wide range of parts, upgrades and restoration support.

What is the Porsche 964?

Built between 1989 and 1994, the 964 was a major leap forward for the 911. While it retained the classic silhouette and air-cooled flat-six engine, over 85% of the components were new or redesigned. Key innovations included:

• Standard ABS and power steering

• Improved aerodynamics and modernised bumpers

• Coil spring suspension (replacing torsion bars)

• All-wheel-drive on the Carrera 4

• Optional Tiptronic automatic gearbox

With around 62,000 units produced, the 964 range offered a variety of body styles including coupe, cabriolet and Targa.

Porsche 964 Model Breakdown

Here’s a quick look at the most common 964 variants you’ll encounter:

Carrera 2 (C2)
Rear-wheel-drive with a more engaging and traditional 911 experience. Available with manual or Tiptronic automatic gearbox.

Carrera 4 (C4)
All-wheel drive made its debut in the 911 range. Offers extra grip but adds a bit more weight.

964 Turbo
Launched with a 3.3L engine in 1990 and later upgraded to 3.6L in 1993. Turbo models are fast, raw and increasingly collectible.

964 RS
A lightweight, no-compromise model aimed at track use. The Carrera RS has become one of the most desirable 964s on the market.

964 Speedster & Targa
More niche offerings with open-top driving character. The Speedster, in particular, is rare and sought after.

What to Look Out For When Buying a Porsche 964

Buying a 964 is about more than just mileage or service stamps. Here are the key areas to inspect:

Engine Condition & Leaks

The 3.6-litre flat-six is durable, but early models were known for cylinder head gasket leaks. Look out for oil drips or grime build-up around the heads and underneath the car. A well-maintained 964 should have a dry engine bay.

Idle Quality & Flywheel Issues

Early C2 Tiptronic models used a dual-mass flywheel that can fail, causing lumpy idle or hesitation. Replacements are available, and many cars will already have had this addressed.

Suspension Wear

The original suspension components are likely to be tired by now. Signs of clunking, uneven tyre wear or vague handling mean a refresh is due. Consider upgrading to performance suspension – Design911 offers a full range of Porsche 964 performance suspension upgrades, including Bilstein dampers, upgraded bushes and lowering kits.

Brakes

Check for disc wear, rust and any juddering under braking. Standard brakes are adequate, but many owners opt for upgrades. You can find OEM replacements or performance brake components at Design911.

Rust Areas

Although the 964 featured a galvanised body, rust can still take hold. Key areas to check include:

• Windscreen surrounds

• Rear window corners

• Jacking points

• Inner wings and arches

• Battery tray

Interior Wear

Seat bolsters, dashboard tops and carpets are all vulnerable to ageing. Interior parts are getting harder to find, but Design911 stocks Porsche Classic interior items, trim clips and restoration kits.

Electrical Faults

Electric windows, sunroofs and heater fans can be problematic. Make sure everything works. The blower motors, relays and wiring are all available from Design911 if replacements are needed.

What Does a Porsche 964 Cost?

Prices have climbed significantly over the past decade, especially for rare or low-mileage models. Here’s a general price guide in the UK market (as of 2025):

Tiptronic-equipped cars are generally more affordable, while manual examples with strong history command a premium.

Upgrades and Enhancements

Many 964 owners like to personalise or subtly modernise their cars. Design911 stocks a full range of upgrades to suit every taste, including:

• Lighting Upgrades: Improve visibility and style with LED options and modern lenses.

• Multimedia and In-Car Entertainment: Install modern head units with navigation and Bluetooth while keeping a classic look.

• Exhaust Systems: Performance exhausts add character and power.

• Wheels and Rims: Upgrade to Fuchs-style or lightweight forged wheels.

• Exterior Styling: RS-style bumpers, spoilers and trim options to give your 964 a custom finish.

Whether you’re restoring to factory spec or going the restomod route, Design911 has the expertise and inventory to help.

Is the Porsche 964 a Good Investment?

The 964 has grown into a serious investment piece. As a bridge between the classic air-cooled era and the more modern water-cooled cars, it appeals to purists and new collectors alike.

Special models like the 964 RS and 964 Turbo 3.6 continue to appreciate rapidly, but even standard Carrera 2 and Carrera 4 models are solid buys — as long as they’re well maintained and original.

Final Thoughts

The Porsche 964 is more than just a classic 911 — it’s a mechanical time capsule that blends analog driving with just enough modern tech to be usable every day. As values rise and parts become harder to find, getting into a good 964 now could be both emotionally and financially rewarding.
