So, My baby hits 50k mark. I bought her an year ago at 42k.
She is 2006 550i and isnt driving in the same quick, quiet and aggressive mode.
Ever since I bought her, I got engine oil changed almost 6 months ago,
Fixed a minor coolant leak and engine oil leak a month ago.

I have no idea what previous owner has changed but my mechanic says everything looks good. I need your suggestions as to what should I get replaced/serviced for engine maintenance.

Any checklist for 40-60k mark?

Thanks!
