I love my m3, but the one and ONLY thing I HATE about it is that there is no m*ther f*ckin dipstick...
To be honest, I also ponder sometimes if the dealership really changed my oil or not. I don't know how to check if the oil is clean or not coz of the lack of a dipstick. The dealer could've just topped my oil off without even changing it.
No dipstick FTL!
