Infiniti knock sensor replacement

Reducing this to four stars, based on the fact that I have just tried to look at a replacement battery for another car in our household, which is currently SORN - We need a battery to make it roadworthy, and the Fixter system won't entertain it, which is an area for improvement for me. Everything else is true and correct, though this is a bit disappointing and we'll now have to look elsewhere. Everything a service based company should be. From start to finish the process was simple, efficient and most importantly, excellent value for money. So many businesses in the UK could learn a thing or two from this organisation. I will go to Fixter first in future and hope that their model continues to remain as just as it is.
