Today I pulled the trigger on a M3 Comp xDrive. Dealer requested a $5k deposit, I was able to talk them down to $2500. That feels like a win, as some other dealers I called wanted a 10% deposit. Once I have an official production status, I’ll update.
This is my 2nd BMW, I’m currently driving a 2023 X5 and that really gave me the BMW bug and sent me down the “rabid” hole 😂🤣😂.
They are saying this should hit production in December or January and be in around April. They actually delivered my X5 a few weeks early, on my first order, fingers crossed they are at least on time or early!
Let me know if you have any questions about specs or ordering process.
What happens if you don’t break it in properly?
The break in period is mainly to seat the piston rings to your cylinder walls properly. In the engine the piston rings rub against your cylinder walls constantly, the tolerances are very tight.
Improper break in can mean the rings wear down too much and that tolerance widens up meaning that gasses can escape around the side of the cylinder and into the crankcase. Also on the flip side, oil can make its way into the combustion chamber easier causing excessive oil consumption.
My BMW tech told me that it can have long lasting effects on the whole drivetrain. All the brand new elements of the car need to adapt themselves to each other. In this period you have a lot of inital friction in the engine and between it’s parts, that’s why you have to do an diff oil change and an oil change right after the period so all the small metal bits that emerged in the breaking in period get removed from the oil system. If you do this too fast (high rpm, high speed) it can result in grooves in the cylinder walls which will have less power and maybe less lubrication than you want as a result. I hope I remembered correctly. All in all it’s a crucial period if you want to have a healthy engine for the rest of your ownership.
