How prices are spread

The middle half of BMW M4 Base asking prices sits between $41,380 and $48,883, and the 2018 model year has a median price of $42,068 against $47,923 for 2020. Market data shows the market is hot, with a typical time to sell of 126 days. Listings last checked on May 1, 2026.

How to buy one

Target 2018 cars with mileage near the 47,186-mile median for that year, or 2020 cars around 41,079 miles, and expect room to negotiate on any listing that has been sitting for more than a year. Use the long time on market and the 29 other listings as leverage, and always get a pre-purchase inspection and service records before committing.
