Specialist in Teesside?

[brianb]

Good morning

My wife's m135i is coming up for service next month and Im keen to use a reputable specialist if possible

can anyone recommend someone decent?

a quick google throws up both www.teessideautotech.co.uk/ and www.sterling-bmw-services.co.uk/ but i have never used either, equally Im not against using the main dealer (cooper's) if this is still regarded as the best option
