I know this is an old thread, but just wanted to update you guys after a couple months of having to get various maintenance things and repairs done.
I went to Bradley Motor Werke for some maintenance items like rear brake change. All the service was fine, then I went in for a serpentine belt tensioner replacement and he ended up charging me over $400 just in labor; I provided the parts. Long story short, its a hit or mis with bradley depending on who he has working in the back.
Thanks to the recommendation of a local 135i driver I sold a shifter to, I've been going to Jon at
