Not bought off them but visited them when we were buying our last MH. They offered to have an MH at a different showroom delivered for inspection if we paid a £200 deposit up front. We were told this deposit would be refunded if we didn't want the vehicle which, if there's no catch, seems reasonable enough. I found their screen prices a bit steep compared to other dealers - we saved 3k buying a lower mileage, better condition van elsewhere athough we didn't push hard on getting a lower price. The chap we spoke to at the Preston branch seemed pretty knowledgeable and there was no hard sell.
