Taj Quick Fit Ltd in Hounslow
Avoid this company!
I brought my car to this place with engine whistling noise. Their "specialist" inform me that tensioner bearing needed to be changed, cost £100.
I asked him if he is 100% sure, he went back to the car and came with another part to be change as well, the belt cost £10 and he said that's it. Few hours later they called me to pick up "fixed" car.
