Independent service, thames valley area

[JonA]

Can someone recommend a good independent garage for BMW service in Thames Valley area (I'm in Windsor.)
Based on my TVR and Porsche experience, I'm automatically assuming main BMW dealer will be rubbish, overly expensive and rude!

Car is a 2002 325. Likely going to need new disks/pads too

Thanks
Jon

Are there not recognised BMW independent specialists around? That's the case with porkers and tvrs - but perhaps bmws are understand well by general garages?
Thanks guys
