we used to deal with one link but didn't get enough work out of it to make up fr the £270 annual fee we had to pay them. We deal with Arval ove the phone for the odd vehicle that we get in and with Arnold Clark for our other main customer (AC are so easy to deal with, they pay a good labour rate and never ask for prices)
We found we were not getting enought fleet work in to cover our costs. The system was quite easy to use though.
