No Reserve: 18k-Mile 1998 BMW M Roadster

The BMW vehicle up for auction is a classic from the late '90s, specifically an M Roadster produced in 1998 with only 18,000 miles logged on its odometer. It's important to note that this isn't your average '98 BMW; it's a rarity, or "unicorn," being part of limited-edition series dedicated to the German automaker's motorsports heritage.
