Looking for a shop in Portland

I just got an E90 M3 and I am looking for a shop in Portland for services/larger maintenance/modifications/etc. Nothing pressing at the moment, but I imagine there will be soon.

Hoping to get some recs from the locals. Thanks!

Bavarian House. Best BMW shop in the NW. Can't recommend them highly enough.

Awesome, thank you

drwankel any recommendations for Seattle area shops? Have only used Eastside Bavarian, but they're very OEM oriented and don't touch aftermarket parts. Told me to replace my NRW spark plug tubes with OEM ones when they removed my plenum

AR Motorsport / AR Auto Service. They work on all our BMWs, street and track and in between.

Motorsport shop is in Tigard off Greenburg, Service shop is in Lake O on Boones Ferry. Can't go wrong at either one, especially if it's just general maintenance and upkeep. Owner is Eddie and races mostly BMWs.

They just had my E92 in there for some suspension work and my E46 is there now for... suspension work. lol.
