Excellent !! My X5 M50d broke down and I really didn’t know where to go, the local dealer wanted more than the cost of the car to do the engine replacement and I asked my mechanic who does my brakes if he knew anyone. He recommended B M engine works and I rang them to get a price, they arranged recovery, replaced the engine, did a few other things that I wanted to doing and within 3 weeks the car was back on the road. I drive a lot to Europe and needed the peace of mind that I wouldn’t be broken down on a motorway somewhere but at the same time I didn’t want to pay ridiculous amounts to the dealer. These guys were more affordable and actually do this work everyday and as such my mechanic said I should go to them ! Cars done 1700 miles since then without any hiccups and I’d swear it’s quieter too Overall very pleased and happy Highly recommended
