[E90F30er]

Hi, do any of you keep a notebook (or electronically) of things such as date, mileage, garage / dealer and thing changed with price? For easy reference? :-)

Also how many miles do your fronts and rears last before reaching say 3mm of tread typically please? How you drive, where you drive, tyre pressures at recommended level, correct wheel alignment and perhaps E9x model, LCI or not will have a bearing on the mileage I guess?

Thank you.
