What will my BMW G29 Z4 sell for on Bring a Trailer?
Every BMW G29 Z4 auction we have on record, grouped the way the listings themselves describe the car, so one version is never averaged with another.
Below is every BMW G29 Z4 auction we have on record from Bring a Trailer's published results, kept apart by variant. We are an official Bring a Trailer Local Partner, so this is the same record we use when a seller asks us what to expect.

Figures are for auctions that ended since Nov 2024. Prices are winning bids; the buyer pays Bring a Trailer's fee on top. "Sold rate" is the share of auctions that met reserve. A variant with fewer than 3 sales shows no median: one or two cars are not a market.

How to read these numbers
- Every price is a completed Bring a Trailer sale and links to its listing. Asking prices are not counted anywhere.
- The price is the winning bid. The buyer pays Bring a Trailer's fee on top of it.
- Variants are never averaged together, and conversions, race cars and projects are listed but left out of the medians.
- Mileage and colors are read from each listing's title and short description. Mileage is rounded there, so a "22k" car may have a few hundred miles either side, and a dash means the listing's summary didn't state it.
- Cars we sold ourselves are marked and open the car's own page, with its photos and history.
