We bought our used van from them.
They seemed as good as any other car dealer, it was very reasonalbly priced compared with others on sale at the time. I suspect from the condition and the fact that they were the registered keeper that they had been using it for hire. There was also some evidence of repaired accident damage on the passenger side. I suspect these were the reasons for the low price but they did not want to give that information.
They probably knew thay had the sale in the bag given that we had taken a 450 mile round trip to see it.
They agreed to fix a few defects before I went back up to collect it. It was not ready on time because they had misdiagnosed the earth shunt as defective leisure batteries. They offered me a demonstraor Cali instead with my van delivered at a later date. I still had my old van so they refunded my train tickets and delivered the van to Leeds, with the earth shunt done, new leisure batteries and all of the other bits and peices that go 'missing' (saftey net, 4th bike holder, tie down kit etc) that they had initially said we would have to pay for.
Overall we were happy, and delivering it to Leeds with the extra bits more than made up for the delay. Whilst not perfect the van was by no means in poor condition and we have 2 small children and don't have to worry as much about the odd extra scratch and scuff on the interior, especially knowing that we paid less for for the van in the first place.
