The 2006 BMW M5 sold for $12,500, and that's a deal.

This beast packs a 5.0L V10 that churns out a factory-rated 500 horsepower. The automatic transmission isn’t as beloved as the manual, but it does make for a more user-friendly daily driver. With 138,600 miles on the clock, this M5 isn't a garage queen, but that’s part of its charm. It's been modified with RPi ram-air induction and a Megan Racing stainless steel X-pipe, likely boosting its power. The seller has taken care of the rod bearings, so it’s ready for action. Sure, there are some cosmetic flaws, but this M5 is still a solid performer for anyone wanting a high-speed daily.

Considering the price, $12,500 is way below our fair value estimate of $15,500. The car sold for about 19% less than that — that's a significant drop for a performance sedan with a pedigree like this. With 35 bids, it’s clear there was strong interest, which usually drives prices up. But in this case, the modifications and high mileage likely kept the final bid lower than expected.

The community was buzzing with excitement over this auction. One user noted, “Congratulations to the winner. You got a great car for a great price.” That sums it up perfectly. This wasn’t just a random sale; it was an opportunity for someone to snag a legendary sedan without breaking the bank.

For buyers on the hunt for a similar M5, keep a close eye on service history and modifications. Not all upgrades are created equal, and some could lead to reliability concerns down the line. Make sure to verify that the important maintenance, like the rod bearings, has been done. Mileage matters too; while 138,600 is manageable, low-mileage examples can command a premium. If you find a well-maintained one, don’t hesitate — you might just score a deal like this one.
