Just picked up my M135i from Bm engine works after having a engine replacement, I’m based near Exeter so was sceptical at first of sending my car away to a garage 200 miles away who I had never heard of, but there weren’t many people around who could do this and nobody who could at the price BM engine works gave. Work was completed quickly and I was kept updated with videos and pictures as the work progressed! I’ll be going up again after 2k miles for the service on my car to maintain the 12month warranty. My experience with bm engine works was a very good one they are very friendly guys and I would use again ( hopefully I won’t need to )
