This BMW 525i Wagon Is Hiding an 8-Series V-12 Under the Hood

Yes, it even has a manual. The perfect vintage sleeper? Maybe.


BMW never built a V-12 5-series, which is a shame. But that hasn't stopped enthusiasts from doing swaps of their own. This E34-generation 5-Series wagon started life out with a base inline-six before it was transformed into the ultimate sleeper. The best part? It's for sale.

This car recently in East Hampton, Connecticut. According to the seller, , it was built by a reputable shop in the Midwest prior to their ownership. (A name wasn't given, but judging how well everything seems to fit together, we're inclined to believe them.) The drivetrain is from a wrecked 850Ci, meaning a 326-horsepower 5.4-liter V-12 sits under the hood, connected to a six-speed manual transmission. Suspension components and the brake system were also swapped over. Other upgrades include a built-in radar detector, 17-inch wheels, a new sound system, a stainless steel exhaust, and a window tint.

The ad doesn't include many pictures, but from what we can see, everything looks neat and tidy, almost as if the car came from the factory with a massive V-12 in the engine bay. Aside from the aftermarket wheels, the only performance mod we can spot is a front strut tower bar.

The car is currently for $17,000, and the seller lists a handful of possible trades they'd also accept. If you're in the market for a practical BMW with some serious firepower, this is the one to have.
