Someone just built the only V10-powered, manual BMW M5 wagon in the US—and it’s up for grabs at just $50K! This unicorn started life as a regular 535Xi, but now it’s rocking an M5 V10, six-speed stick, and all the M goodies. Sure, it’s got some quirks (mileage mystery, a few dings), but where else are you gonna find a DIY M5 wagon like this? Would you roll the dice on this beast? #Cars #BuyingCar #BMWM5
