Best Value Car ON THE MARKET
By Ryan on 6/29/2026 5:05:47 AM
I’ve wanted a M4 for 5 years. I have had this chassis 3 times, all with a slightly larger i6 each time. The M4 Is the 3rd 4 series chassis i’ve owned and it is extremely different than the others in the best way possible. This car has a DCT transmissions similar to cars such as like ferraris, porsche and lamborghini. It has a carbon roof that is also found in those category’s of cars along with a twin turbo, quad exhaust bucket seats and weight reduction everywhere. The aggressive styling is the chef’s kiss, aggressive body lines and 666M wheels make the car feel special. Simple’s put this car is extremely over engineered in the best way possible! Maintenance is doable at home with proper equipment, labor is not extensive unless you plan to modify which this platform welcomes it kindly on the aftermarket. I put 5k maintenance and parts along with Carbon fiber genuine pieces to make it my own. in + it’s better looking and cheaper than the M3. Never selling this car. 6 month review 10/10 - 5.0
Awesome Driving Machine
By Mike on 9/17/2025 1:30:12 PM
I bought a 2018 M4 convertible online--my first time purchasing before driving a car. The M4 is exactly as advertised. It is responsive and powerful when required but tame enough for a leisurely drive on a Sunday afternoon. Of course, it looks terrific in my driveway and on the move. - 5.0
M4 Competition
By Earl on 1/5/2024 6:06:43 AM
I can tell you now, I've had a 2015 and then a 2018 M4 Competition. I have moved to an electric BMW I4 but that 2018 M4 is my favorite all time car. I never had any issues. It looks and sounds good. The handling is perfect, especially in sport mode which I drive most of the time. I had mine tuned and it went from 444 to 549 HP for $800. Wow, did that M4 fly. I miss the car very much. The M4 as a used car is a great deal. Have fun.
