Very good. My Bmw 3series i318 from 2002 was having heavy misfires, rough idles and would lose power in the middle of driving.
I decided to take to to C and R motors. Since they were working on a few cars already so until its my turn it would take an hour or two, so i deiced to leave the car there and come back home.
Upon starting work on my car, i was kept up to date on the situation, what they found and what they were doing.
The next day morning i was given a call by them telling me the car is ready to pick up.
To my surprise the car had been fixed and it turns out to be a much more simple problem compared to what i actually thought. I believe it was the VVT sensor acting up.
I was charged £180 with Vat for the manual labor/replacing Spark plugs with higher quality ones and the diagnostic test itself.
Overall i would recommend this place, they know what they are doing and they do their job honestly.
