We have been with 1link for a couple of years now. All it enabled us to do was continue with the lease companies we were dealing with before they signed up to 1link.Thats the key its to the benefit of the lease companies who now dont have to answer phones etc its all done via ilink.
We have not to date received any extra work.
The system is OK if you are using it regularly bit like getting used to MOT computerisation !!!
My advice as those before dont sign up expecting to get loads of extra work.
