Buyer's Guide

Porsche 964 911

1989–1994

Overview

The 964 is where the 911 got modern underneath without losing what makes it a 911: coil springs, power steering, ABS, and the first Carrera 4, all wrapped around an air-cooled flat-six. Prices have climbed with the rest of the air-cooled market, which makes a thorough inspection non-negotiable. The known weak spots are oil leaks, the dual-mass flywheel, the twin-plug distributor, and head studs. Pay for a leak-down test and a specialist's eye before you commit.

What to Pay

Prices checked January 2026. Rough US market ranges. Location, history, and options move these a lot.

Project

$35,000–$60,000

Cars needing engine work or with significant issues. Still valuable due to air-cooled premiums.

Driver

$60,000–$90,000

Running and driving with some needs. Good entry point for air-cooled ownership.

Excellent

$90,000–$140,000

Well-maintained Carrera 2 or C4 with documentation. Clean examples.

Concours

$140,000–$250,000+

RS, RS America, or exceptional Turbo models. Low miles, fully documented.

Which One to Buy

Carrera 2

1990–1994

Rear-wheel drive with the 3.6L and 247 hp. Lighter and more pure than the C4, and the one most drivers want.

Desirability High

Carrera 4

1989–1994

All-wheel drive, and the first 964 on sale. Heavier, but more planted in bad weather.

Desirability Medium

RS / RS America

1992–1994

The lightweight specials. The European RS had 260 hp and a stripped interior; the RS America was a pared-back Carrera 2 for the US. Both are serious collector cars.

Desirability High

Turbo (965)

1991–1994

The widebody Turbo, with a 3.3L (320 hp) or later 3.6L (355 hp) flat-six. Seriously fast, and seriously expensive to maintain.

Desirability High

Targa / Cabriolet

1990–1994

The open cars. The Targa has a removable roof panel, the Cabriolet a full folding top. Less stiff, but popular.

Desirability Medium

Walk Away If…

  • Oil smoke indicating worn engine internals
  • Timing chain rattle on cold start
  • Unknown service history
  • Evidence of water damage or flooding
  • Structural rust in rockers or shock towers
  • Turbo models with boost control issues
  • Heavy modifications without documentation
  • Salvage or rebuilt title

Pre-Purchase Inspection

What I'd check on any 964 before buying, with a rough cost if it's bad. Print it and take it with you.

Engine (check first) 5 checks
  • Oil Leaks Air-cooled 911s leak oil—some is normal. Check chain housings, valve covers, and case halves for excessive leaks. If bad: $1,000–4,000 depending on location
  • Timing Chain Tensioners The dual-row timing chains have spring-loaded tensioners. Listen for chain rattle on cold start. If bad: $2,000–4,000
  • Compression and Leak-down Have a compression and leak-down test performed. Should be within 5% across cylinders. If bad: Engine rebuild $15,000–30,000
  • DME and Fuel Injection Check for smooth idle and proper fuel mixture. The Bosch Motronic system is reliable but sensors fail. If bad: $500–2,000
  • Turbo System (965) Check for shaft play, boost leaks, and wastegate operation. K26/K27 turbos are expensive to rebuild. If bad: $3,000–6,000
Transmission & Drivetrain 4 checks
  • G50 Transmission Test every gear. The G50 five-speed is tough, but synchros wear. Check that it doesn't pop out of gear. If bad: $2,000–5,000 for rebuild
  • Clutch Test engagement—should be smooth and grab mid-travel. Clutch replacement is labor-intensive. If bad: $2,000–3,500
  • CV Joints Listen for clicking in turns. Check boot condition for tears. If bad: $500–1,000
  • AWD System (C4) Test for proper engagement. Check for differential noise. System adds complexity. If bad: $2,000–5,000
Suspension & Steering 4 checks
  • Coilover Condition 964 introduced coil springs. Check for leaking shocks and worn bushings. If bad: $1,500–3,000
  • Power Steering Check for leaks from pump, rack, and lines. Listen for whining indicating low fluid. If bad: $800–2,000
  • Control Arm Bushings Front and rear bushings wear. Check for play and cracking. If bad: $600–1,500
  • Wheel Bearings Jack up each corner and check for play. Listen for grinding while driving. If bad: $400–800 per corner
Body & Electrical 4 checks
  • Rust Inspection Check rocker panels, floor pans (especially under battery), and around windshield. Earlier cars rust more. If bad: $2,000–10,000+
  • Wiring Condition 964 uses biodegradable wire sheathing that rodents love. Check for damage. If bad: $1,000–5,000
  • Targa/Cabrio Seals Check for leaks and proper seal condition on open-top models. If bad: $500–1,500
  • HVAC System Climate control can be complex. Test all functions including A/C. If bad: $500–2,000

Worth Paying Extra For

  • Carrera 2 manual for purest driving experience
  • Complete service records from Porsche specialists
  • Recent major service (clutch, timing chains if needed)
  • Rust-free body, especially dry-climate cars
  • Original paint and interior
  • Sport seats option
  • Limited-slip differential
  • Books, tools, and documentation

Fuel economy

Before You Buy

  • The 964 is one of the most usable air-cooled 911s: modern enough for regular driving, still air-cooled at heart.
  • Drivers prefer the Carrera 2. The C4 is more forgiving in bad weather.
  • Some seepage is normal. Real leaks aren't. Learn the difference.
  • Find a specialist who knows air-cooled cars before you need one.
  • Budget for a pre-purchase inspection by someone who knows 964s, with a leak-down test.
  • RS America values have climbed a long way. Verify authenticity carefully.
  • The G50 gearbox is tough, and parts are easy to get
  • Rennlist and the Pelican Parts forums both have deep 964 knowledge.
  • Budget for engine mounts and suspension bushings. At this age they're due.
  • A well-maintained 964 will last indefinitely.
