I used Lube Mobile to replace the timing belt and water pump on my girl friends car after it had been recommended by another service agent. Lube Mobile came in 25% cheaper than the quoted price from the other service centre, In addition, they were prompt friendly and knew what they were doing.
A few weeks later the car broke down and wouldn't start. I contacted Lube Mobile and they came out within the hour to check that it wasn't there workmanship that had been the cause of the breakdown. It wasn't and the mechanic spent quite some time trying to sort the problem out, which he did. The cost for parts and labour were well within reason for what he did and I wouldn't hesitate recommending their service to anyone.
