I had a new engine put in by London Engines they promised it within 7 days which they delivered on. They were brilliant and I have been delighted with the result, the ladies that dealt with me were so understanding and totally empathised with me, they even offered to send videos of them working on my car for reassurance if i wanted it. I would really recommend their services it is first class and far in excess with what you would expect of a garage. I felt as if my car was in a private hospital without the excessive costs and instead of a car it was a loved one which of course my car is. :)
