Compare like with like before comparing prices
The 2005 Infiniti G35 name covers cars with different bodies, transmissions and driven wheels. Record those details for each candidate before comparing asking prices or service advice. A coupe with aftermarket suspension and a standard G35x sedan present different questions even when their mileage is similar.
Infiniti’s January 2005 coupe specifications (archived original PDF) and its 2005 sedan launch release, reproduced by Infinitihelp establish the following U.S. model distinctions. Confirm the VIN and factory equipment for the individual car.
On a narrow screen, scroll the table sideways. Keyboard users can focus the table region and use the arrow keys.
| Variant | Transmission and drive | Comparison question |
|---|---|---|
| G35 coupe | Five-speed automatic or six-speed manual; rear-wheel drive | Do its two-door access and four-seat layout suit the usual passengers? |
| G35 sedan | Five-speed automatic or six-speed manual; rear-wheel drive | Which equipment and service history belong to this exact version? |
| G35x sedan | Five-speed automatic; all-wheel drive | Has the fitted AWD system and its maintenance been included in the inspection? |
The factory documents list different engine outputs for automatic and manual versions. Keep any quoted output attached to the correct year and transmission; a seller’s performance number does not establish the present mechanical condition.
Try the ordinary trip
Test seating, entry, visibility and cargo access in a stationary inspection before a road demonstration. For the coupe, try rear-seat entry with the front seats set for the intended occupants. Bring dimensions for the largest regular luggage item and check the opening as well as the space beyond it. For either body, operate the equipment you expect to use every day.
Ask which convenience features are factory fitted and which have been added. Check the operation of aftermarket audio, lighting or other electrical equipment and request installation records. Note features that could not be demonstrated so they remain visible in the decision.
Build a modification inventory
For every modification, record the manufacturer, part number, installer, date and reason for the change. Separate documentation of the component from evidence that it was installed and checked correctly on this car. Ask whether the original parts are available and whether other changes were required.
On a narrow screen, scroll the table sideways. Keyboard users can focus the table region and use the arrow keys.
| Area | Useful records | Independent inspection question |
|---|---|---|
| Wheels and tires | Front and rear sizes, wheel dimensions, tire specifications and receipts | Are fit, clearance, condition and compatibility appropriate for the exact variant? |
| Suspension | Component list, installation invoice and alignment report | What changed in ride height and geometry, and is the installation suitable? |
| Brakes | Parts and installation records | Are components matched, correctly fitted and functioning as intended? |
| Engine, exhaust or software | Hardware list, calibration details and supporting documentation | What has changed, and does the car meet applicable inspection and emissions requirements? |
The 2005 coupe specification sheet lists different front and rear tire sizes for its factory wheel packages. Record both axles. Have a qualified shop establish the correct setup for the particular car; a wheel diameter alone does not establish fitment. Modified examples need the same scrutiny even if the seller describes the parts as an upgrade.
Connect driving observations to a written assessment
Agree an inspection that includes engine and cooling condition, transmission, clutch where fitted, driveline, brakes, steering, suspension, tires, body structure and evidence of previous repairs. Ask for an explanation of oil-use history and any repeated top-ups or warnings, supported by records where possible. A broad reliability claim cannot settle the condition of one vehicle.
During an appropriately arranged road demonstration, note the conditions of vibration, pulling, noise or shift concerns and give them to the inspector. Keep the drive ordinary and lawful; a purchase inspection does not require a performance test. Request a written result separating diagnosed issues, routine maintenance and areas not assessed.
Check the VIN at NHTSA Recalls and request manufacturer campaign and completion records. The online VIN search omits completed recalls and can omit recalls more than 15 years old. Keep the result with its search date.
Price the installed condition
Compare candidates using the same columns: daily fit, documented configuration, condition, modifications, required work and unknowns. An inexpensive car can demand more investigation; a standard-looking car still needs a full inspection. The inspection guide helps define the appointment, and the service-advisor guide helps turn observations into a clear diagnostic request.
