We sell both new and used parts, so we have no reason to push you either way. The honest answer is that some parts are an excellent buy used and some are a false economy that costs more within a year. The dividing line is simple: parts that wear or age should be new, and parts that are sealed assemblies or simply not made any more are where used shines.
Never buy these used
These parts either wear by design, degrade with age regardless of miles, or cost so little new that the used saving is not worth the risk.
- Brake pads, rotors, drums and shoes. They are wear items; a used set has an unknown fraction of its life left and new ones cost little more.
- Filters, belts, hoses, gaskets and seals. Rubber and paper age whether or not they are used.
- In-tank fuel pumps. The pump ages with the fuel it sat in; a used pump from a 12-year-old donor is a 12-year-old pump.
- Water pumps and timing components. The labor to reach them is the expensive part, so install new and do it once.
- Batteries, spark plugs, ignition coils, oxygen sensors and other consumable electrics.
- Tires. Age cracks rubber from the inside; a used tire with deep tread can still be unsafe.
Buy these used with confidence
Sealed assemblies from a low-mileage donor are mechanically identical to new, and body and trim parts are often not made new at all for a 15-year-old vehicle.
- Engines and transmissions, with the mileage verified and the warranty terms in writing.
- Transfer cases, differentials and axle assemblies, matched to the ratio and shift type.
- Doors, hoods, fenders, tailgates and bumpers in the factory color code. Used saves the paint job.
- Headlight and tail light assemblies, especially HID and LED units where the aftermarket version is poor.
- Mirrors with heating, power-fold, cameras or blind-spot sensors.
- Wheels, seats, consoles, interior trim, radios and instrument clusters.
It depends: modules, alternators and AC compressors
Control modules are a good used buy when the part number matches exactly and the module does not need programming, which is common on older vehicles and rarer on newer ones. Ask before buying; we check by make and year.
Alternators and starters are usually better remanufactured than used, because a reman unit has new bearings, brushes and a warranty for a similar price. Used makes sense for rare vehicles where no reman exists.
AC compressors are the trap. A used compressor from a donor with a failed system carries debris that will destroy the next system. Buy new or reman, and replace the drier and expansion valve with it.
Call with the part and the VIN. We tell you whether used, remanufactured or new is the smart buy for that part, and quote the right one.
Questions we get about this
Not necessarily. A well-maintained 90,000-mile engine from a rear-ended vehicle is a normal used engine. What matters is verified mileage, the reason the donor was scrapped, and the warranty. We tell you all three before you decide.
For HID, LED and adaptive units, usually yes. The electronics inside are vehicle-specific and the cheap aftermarket versions fail or fit badly. For plain halogen housings, a quality new aftermarket unit is fine.
Yes. If you ask for a used fuel pump or brake rotors we will quote new or remanufactured instead and explain why. Selling you a part that fails in six months helps nobody.
