We've seen SUVs being turned into dragsters and track toys, and we've seen sports cars being transformed into off-roaders. Even automakers are getting in on the latter, too. Huracan Sterrato, anyone?Of course, there are those who have built off-roaders out of cars that were never meant to go off the beaten path. From time to time, these come up for sale in search of a new owner who can appreciate the unusually interesting build.Savestep/Bring a TrailerThe BackstoryWhat we found on Bring a Trailer is a 2005 BMW Z4. Internally known as the E85, a 2.5i model is currently valued at around $10,800, based on Classic.com's assessment. But what we have here probably won't fall under typical evaluation. That's mainly because the seller went ham with the off-road mods.AdvertisementAdvertisementThis particular car started out in life as any other Z4 2.5i, and relatively well specified as it comes equipped with a Sport Package. But none of that really matters, because it's been given a lift kit and all-terrain tires, so it's far from your usual Z4. Also attached to it is a nudge bar at the front, a carrier basket, and a generous helping of driving lights.It's admittedly a little weather-worn, but a good degree of mechanical work has been done to it. It includes a fresh service, a new coolant expansion tank and hoses, and other plastic components under the hood have been replaced.Savestep/Bring a TrailerThe OfferSpecificationDetailMakeBMWModelZ4 2.5i Sport (E85)Year2005Mileage92,961 miles indicatedEngine2.5-liter M54 inline-sixPower189 horsepowerTransmission6-speed automaticDrive typeRear-wheel driveExterior colorSatin BlackInterior colorBeigeWheels17-inch Style 79 split 5-spoke alloy wheelsSuspensionMacPherson strut front, multi-link rearBrakesFour-wheel ventilated discSteeringElectric rack and pinion steeringCurrent bidBidding OpenInterested in the car?

It's not every day one gets to see a lifted Z4, let alone one for sale. While the roadster isn't particularly rare with nearly 181,000 made, the unique build adds a touch of personality. All it needs now is an eccentric buyer who can truly appreciate it.Savestep/Bring a TrailerSavestep/Bring a TrailerAdvertisementAdvertisementView the 8 images of this gallery on the original articleThis story was originally published by Autoblog on Sep 1, 2026, where it first appeared in the Car Buying section.
