Porsche 964 and 993 Prices in 2026: What a Donor Car Really Costs
Porsche 964 and 993 Prices in 2026: What a Donor Car Really Costs
Every backdate starts with a donor car, and the 964 and 993 are the two air-cooled 911s most builders choose. Prices have moved a long way in the last decade. Here is where the market sits in 2026 and what to look for before you buy.
Porsche 964 prices (1989–1994)
The 964 was the first 911 with power steering, ABS and coil-spring suspension, which is exactly why it makes such a good starting point for a backdate. According to CLASSIC.COM market data in September 2026, most standard 964 variants sit between roughly $60,000 and $200,000, with a typical Carrera 2 trading between about $71,000 and $112,000 depending on gearbox and body style.
The headline “average” price of a 964 is much higher, at around $264,000, because rare cars like the Carrera RS and Turbo pull the number up. For a backdate donor, the numbers that matter are the Carrera 2 and Carrera 4 coupes and Targas.
Porsche 993 prices (1994–1998)
The 993 was the last air-cooled 911 and is widely regarded as the most refined. CLASSIC.COM data puts the market in clear bands:
| Model | Typical value (US, 2026) |
|---|---|
| 993 Carrera (base) | ~$69,000 – $99,000 |
| 993 Carrera S / Carrera 4S | ~$168,000 – $189,000 |
| 993 Turbo | ~$256,000 |
| 993 GT2 | $1.4 million and up |
For a backdate, a base Carrera coupe is the sensible donor. Wide-body S, 4S and Turbo cars are better left original, because their value is tied to originality.
What drives the price of an air-cooled 911
- Gearbox: manual cars command a clear premium over Tiptronic.
- History: a full service file and matching VIN and engine numbers add value. Our Porsche VIN guide shows how to check them.
- Corrosion and accident history: structural rust or poorly repaired damage is the most expensive problem to put right.
- Mileage and engine condition: less critical for a donor, because the engine will be rebuilt anyway.
Buying a 964 or 993 as a backdate donor
A donor car is judged differently from a collector car. Cosmetic condition barely matters, because the car will be stripped to a bare shell. What matters is a straight, honest chassis and a clean title. Paying extra for low miles or perfect paint on a car that is about to be rebuilt is money you will never see again.
That is why many clients let the builder source the donor. At Shoreline, every build starts with a hand-picked 964 or 993, inspected before purchase. If you are still deciding between the two platforms, read Porsche 964 vs 993: which is the better platform for a backdate?
Which variants cost more?
Within each generation, the specific model matters as much as mileage. As a general rule, from most to least expensive:
- Limited and motorsport models such as the 964 RS and 993 RS, the 993 GT2 and the 964 Turbo S sit in a market of their own.
- Turbos: the 964 Turbo and especially the twin-turbo, all-wheel-drive 993 Turbo carry a large premium over naturally aspirated cars.
- Wide-body naturally aspirated cars: the 993 Carrera 4S and Carrera S, with their Turbo-width rear arches, are the most sought-after regular 993s.
- Carrera 2 and Carrera 4 coupes form the core of the market and make the most sensible backdate donors.
- Targa and Cabriolet models vary: the 993 Targa's sliding glass roof has its fans, while cabriolets are usually the least expensive way into either generation.
Transmission matters too. Manual cars command a clear premium over Tiptronic automatics in both generations.
Pre-purchase inspection checklist
An independent inspection by an air-cooled specialist is the best money you will spend. At a minimum, it should cover:
- Chassis and history: matching numbers, service records and any evidence of accident repair. Our VIN and chassis number guide shows how to read the numbers.
- Oil leaks: the 964 is known for leaks from the cylinder base and head gaskets, and a leak-down test tells you far more than a test drive.
- Dual-mass flywheel (964): original units can fail, and most cars have been converted by now. Ask for proof.
- Rust: check the front pan, the battery box area, the door bottoms and the rear arches.
- Secondary air injection (993): a known weak point that can cause warning lights and failed emissions tests.
For a donor car that will be fully rebuilt, some of these matter less. A tired engine is fine if it will be rebuilt anyway. A straight, honest, rust-free shell is what really counts.
Donor price vs total build cost
The donor is only part of the total. A full backdate, including the body-off rebuild, engine, gearbox, suspension, paint and interior, costs several times the price of the car you start with. Our breakdown of what a Porsche 911 backdate actually costs covers every line item, and Shoreline’s custom Porsche 911 backdate builds start from $350,000 for a 2026 build slot.
Frequently asked questions
How much is a Porsche 964 worth in 2026?
A standard 964 Carrera 2 typically trades between about $70,000 and $110,000 in the US, depending on mileage, gearbox and history. Rare RS and Turbo models are worth far more.
How much is a Porsche 993 worth in 2026?
Base 993 Carrera models generally trade between about $69,000 and $99,000, Carrera S and 4S models around $168,000–$189,000, and Turbos around $256,000, based on CLASSIC.COM data.
Is it cheaper to buy a finished backdate or build one?
Buying a donor and commissioning a build gives you control over the specification and history. Finished examples rarely come up and usually sell close to the cost of a new build.
