Ordered an oil cooler thermostat yesterday, it’s in my hands today, VIC to WA. Unreal service!

First time at Southern BM today and it won't be my last. Efficient and quality service as I'd expected at a much more reasonable price than a BMW Dealer. The only downside, you'll drop your car off and will end up drooling over the m3s and m4s out front!

Fantastic customer service from the team at Southern BM. Expertly repaired my 2011 323i and did so without the attitude and excessive cost of a dealer. Thank you and I will be back for all future servicing.

I Bought my M Performance Brake Kit here and installed today. I got my oil changed. Love the service as always. I only bring my cars to this place eventhough I live in the north side of Melbourne.

Andrew Brien @ Southern BM has been helping me for years with my BMWs - he is extremely astute and has a refreshingly customer-first mentality. I trust him to do the best work and only the best!
