01 / The useful difference

A marketplace that speaks fluent project car.

Broad marketplaces make you work around the listing. Garage Exchange makes the listing work for the build — with the context that tells you whether a part is actually useful.

Fitment that holds up

01

Year, make, model, measurements, and the notes a builder actually checks.

Condition without guesswork

02

Used, surplus, and specialty parts get the photos and context they deserve.

Shipping on real-world terms

03

Sellers set the shipping plan, including the oversized stuff other marketplaces avoid.

02 / How it works

From crate dust to road time.

01

List the useful details

Turn shelf inventory into a clear part record with photos, fitment, and measurements.

02

Find the exact piece

Search like a builder: by vehicle, spec, condition, or the odd detail that matters.

03

Move the project forward

Connect with a seller, sort shipping between you, and get the hardware into the build.

03 / For builders

Keep good hardware in motion.

SELLERS

Your spare parts have a next chapter.

Give surplus, take-offs, and the “someone will need this” pile a proper record — then let the right builder find it.
