Our camshaft broke on our 10yr old Discovery. We contacted various companies for quotes. 4x4 Engine Rebuilds rang us back immediately and emailed over a quote. They came in with the cheapest quote and had good reviews so we went with them. They kept us up to date with their findings (they discovered it had had a previous rebuild) and put in another reconditioned engine-all within their original quote. We met them when we collected the vehicle and they were very friendly and keen to explain what they had done. We're very happy with their work and although we don't usually write reviews we wanted to in this case.
