Hello @Twin Turbo Thank you.
Thats the thing I dont know any independent specialists for this vehicle per say. But Im hoping to find someone here.
So far ive been doing all the usual customers' routines.
Yes service records is a requirement of mine.
I wont say Im mechanic-good but Ive googled and youtubed quite an amount of posts regarding e39 on what to look for and common maintenance, issues and checklists, etc.
Lets see, fingers crossed.
