Spend enough time reading car reviews, and you’ll probably notice a trend among writers. We all love wagons, despite the fact that almost nobody in the United States buys them anymore. If there’s a wagon that could appeal to almost anyone, however, it’s this m2003 BMW 540i M Sport with a very special engine swap. It’s up for auction right now and could be yours – or mine.

It doesn’t get much better for a car nerd than this. The 2003 540i Sport Wagon has had its engine swapped for an S62 4.9-liter V8 and a six-speed manual transmission.

For those of you not obsessed with E39 generation 5-Series cars, that’s the engine from the M5 of the time. Here, it sounds every bit as raw and powerful as it does in the car it originally came from, and the six-speed manual gearbox makes this an enthusiast’s dream.

Inside, the black leather appears to be in great shape, considering the car’s advanced age and mileage, though this wagon is lacking the in-dash navigation system that the M5 carried at the time. It’s probably for the best, given that an 18-year-old computer would feel absolutely ancient compared to even the cheapest infotainment system today.

This auction is a little more than halfway through and the current bit is just over $20,000. There’s quite a bit of time left for that to climb substantially, but at even twice the price it’d hard to feel cheated if you won.

There’s no navigation here, but 20 years haven’t been kind to the M5’s system, anyway.Bring a Trailer
